Overview
The param gui program is a Graphical User Interface (GUI) to edit the parameters of a FTOOLS
parameter file. The actual GUI depends on the content of the parameter file *.par. Additional
GUI comments in the parameter file can define a more user friendly GUI. But it is always possible
to use a standard FTOOLS parameter file to open a GUI window and to edit the parameters, to
save them and to start the corresponding program.
Beside the param gui program a library libparam gui.a is available to call this GUI from an application program. Unfortunately the interface is not yet described. Please send an email to
[email protected] if you want to use this library.

How to start the param gui program
After a successful installation ( see http://isdc/index.cgi?Soft+astroroot ) the program is installed
in the bin sub-directory of the installation directory. The program has one mandatory and one
optional parameter. The first program parameter defines the parameter file. It is not necessary to
write the extension .par. The program will look for the parameter file in the directories defined
by the environment variable PFILES. The program title bar shows the the full path of the used
parameter file.
The second, the optional program parameter defines the program which can be started with the
Run - button of the GUI. If it is not defined the GUI will start the program named as the parameter
file but without extension .par and without path. It is assumed that the corresponding program
is in one of the $PATH directories.

Hints for the User
• Move the mouse on top of the parameter name to see the parameter prompt in a tool tip
(help balloon).
• The number entries for integer and real values have on their right side small buttons to
increase and decrease the numerical value in the field. They also support using the up and
down cursor keys to change the numerical values. The step size can be selected with control
and shift keys:
-shift
control
shift-control
small step (1 unit/factor of
medium step (10 units/factor
large step (100 units/factor
huge step (1000 units/factor
3)
of 10)
of 30)
of 100)
The steps are either linear or logarithmic. The default behavior is linear, but it can be
changed by pressing the alt key at the same time.
• It is possible to select compresses FITS files (*.fits.gz) with the browse - button of text and
file entries: Select first an other file filter in the file selection window before selecting a file.
The filename without .gz is copied into the entry field of the file and string widget.
• If the entry field for file names or strings is too short to show the full text increase the width
of the whole window. This will increase the width of the entry field as well.

Modifications of the Parameter File
The look and feel of the GUI is controlled by the parameter file of the associated executable.
First the standard parameter lines are interpreted and for each line a widget is created. The type
of the widget depend on the data type of parameter. (See section 4.1 Widgets)
Beside that special comment lines modify the GUI. Each of these modification comment line must
start at the beginning of the line with
# GUI
These 5 characters including the space are the key for the GUI to find more information about a
widget. Following this key one ore more fields are allowed. The fields are separated by a comma
(,). Blanks and tabs just before and behind the comma are ignored.
The first field is always the parameter name. Note: there must be no comma between the key
# GUI and the parameter name. Following fields define attributes for the widget of the given
parameter. (See section 4.3 Attributes)
Here are some examples of these modification comment lines:

Z:output, DISABLE:mode=TIMING | SPECTRAL
Z:output, DISABLE:mode=TIMING | SPECTRAL
As shown above beside modification comment lines for parameters also modification lines which
define ”group widgets” like frames, folders and windows are allowed. For more information see
section 4.1.2 Group Widgets.
A modification comment line for a parameter MUST be written in the parameter file
after the parameter definition line!
4.1
Widgets
Each parameter in the parameter file builds one widget, called entry widget. Beside these widgets
three further widgets can be build. These parameter independent widgets group several entry
widgets and they are called group widgets. Frame, window and folder are implemented as group
widgets.
4.1.1
Entry Widgets
• check box widget
A check box widget is created for every boolean parameter (b). Mark the check box to set
the boolean parameter to yes.
Depending on the state of this widget other widgets can be disabled or enabled. See attribute
DISABLE: in section 4.3 Attributes.
• integer entry widget
An integer entry widgets is created for integer parameters (i) as long as no list of accepted
values are defined in the min field of the parameter definition in the parameter file. See also
section 3 Hints for the User.
• real entry widget
An real entry widgets is created for real parameters (r) as long as no list of accepted values
are defined in the min field of the parameter definition in the parameter file. See also section
3 Hints for the User.
GADC – param guiUsers Manual – Issue 1.1
2
• text entry widget
A text entry widget is created for string (s) and for file (f) parameters as long as no list of
accepted values are defined in the min field of the parameter definition in the parameter file.
If the parameter is of type file (f) or if the attribute DOL: is defined for the parameter a
”browse” button appears on the right side of the text entry field. With this button a file or
a DOL can be selected, respectively.
• combo box widget
A combo box is created for all parameters except boolean if a list of accepted values is
defined in the min field of the parameter definition in the parameter file. As soon as the pipe
character ’|’ is part of the min field a combo box is created. All in the min field listed and
by ’|’ separated values are available for selection in the list box of the combo box.
Depending on the selected item in the combo box widget other widgets can be disabled or
enabled. See attribute DISABLE: in section 4.3 Attributes.
4.1.2
Group Widgets
Group widgets have in the first field of the # GUI comment line an identifier instead of the
parameter name for entry widgets.
• Frame Widget
A frame is just a rectangle area with a title (attribute NAME:). It is recommended to specify
the width (attribute W:) and the height (attribute H:) of a frame.
The identifier of a frame is FRAME
• Window Widget
A window widget is a new window on the screen and an associated button in an other
window. The user can open the new window by pressing this button. The attribute NAME:
must be defined for a window widget! It is the Z - coordinate of the window and the text in
the button. The coordinate attributes (X:, Y: and Z: ) define the position of the associated
button not of the window. To place a widget in this window the attribute Z:window name
must be defined for that widget.
The identifier of a window is WINDOW
• Folder Widget
A folder widget consist of several tabs. Each tab has a card with a name. This name is at
the same time the Z - coordinate of the tab. At a given time only one tab with its widget is
visible, while the other tabs are hidden ”behind” this so called top - tab. The different tabs
are defined with the TABS: - attribute which is required for this widget. To place a widget
in one of the tabs the attribute Z:tab name must be defined for that widget.
The size of a folder widget depend on the size and position of the widgets in all the tabs of
the folder. Therefore the attributes W: and H: cannot be defined for a folder widget.
The identifier of a folder is FOLDER
To create more than one group widget of the same type or to define attributes for a group widget
in more than one line in the parameter file the widget must have a unique identifier. Therefor it is possible to increase the widget specific identifiers by further characters. For example
FOLDER name1 and FOLDER name2 are valid folder identifiers for two different folders.
4.2
The Coordinate System or the Layout
To place a widget in its window a three dimensional coordinate system is chosen. The X and Y
coordinates are in units of a character size. (0/0) is at the upper left corner of a window. A folder
has its own X/Y coordinate system where (0/0) is at the upper left corner of the tabs. The actual
GADC – param guiUsers Manual – Issue 1.1
3
coordinate values can be a fraction of a unit.
The third dimension, called Z, consist of different layers. Each layer has a name. A layer can be
a window or a tab of a folder. The main window, for example has the Z - coordinate ”main” and
all hidden parameters are by default located in a window with a Z - coordinate named ”hidden” .
The Z - coordinate of a tab is the text on its card. To place a widget on a specific window or tab
an attribute (Z:name) must be defined.
4.3
Attributes
Attributes are defined in a modification comment line (see section 4 Modifications of the Parameter
File). Each attribute consist of an identifier and a value. The last character of an identifier is always
a ’:’. Attributes are separated by commas ’,’ in the parameter file. There is nearly always a default
value for each attribute. Exceptions are clearly mentioned in the following description of each
attribute. Note: not every attribute is recognize by each widget. See the table in section 4.4
Recognized - Attributes to verify which attributes can be used to modify a given widget.
• X:
Defines the X position of the left edge of a widget on the window or on a tab. To use this
value also the Y: - attribute must be defined for the same widget! If the Y: - attribute is not
defined the default value is used.
See also section 4.2 The Coordinate System or the Layout.
The default value is 0.
• Y:
Defines the Y position of the upper edge of a widget on the window or on a tab. To use this
value also the X: - attribute must be defined for the same widget! If the X: - attribute is not
defined the default value is used.
See also section 4.2 The Coordinate System or the Layout.
The default value is 2 more than the previous widget. The default value of the first widget
is 0. Note: first the position of all widgets for which the X: - and Y: - attributes are defined
are placed on the window or tab. Than the Y - position of the other widgets are determined
by increasing the Y - coordinate by 2 starting with the largest predefined Y - position.
• Z:
Defines the third dimension, the window or the tab of a folder, in which the widget will be
visible. The value of this attribute therefor is not a number as for X: and Y: but a name.
See section 4.2 The Coordinate System or the Layout for more information about the Z dimension.
The default value is main, which is the Z - coordinate of the first window.
As exception the default value for hidden parameters is hidden, which is an other always
available window. This 2nd window can be opened by a button of the main window.
• W:
Defines the width of the widget. The parameter name in front of each widget is not included
in this width.
The width cannot be define for folders.
The default value depend on the widget:
– check box: 16 units
– int entry: 14 units
– real entry: 14 units
– text entry: is either the global attribute TEXT W or FILE W for string and file parameters, respectively. If these global attributes are not define their default values are
used (31 or 81 units). The button of the text entry widget is included in the width.
GADC – param guiUsers Manual – Issue 1.1
4
– combo box: 6 units more than the largest name of all entries in the combo box.
– frame: 16 units
– window: 10 units (this defines the width of the associated button to open the window)
• H:
Defines the height of a widget. This attribute is recognized only by frames. The height of
all other widgets is 2 units.
The default value for frames is 6 units
• NAME:
This attribute overwrites the parameter name on the GUI for entry widgets. It is the title for
frame widgets and the Z - coordinate and the button text for window widgets. This attribute
is required for windows!
There is no default value.
• NAME W:
Defines the width of the parameter name or the value of the NAME: attribute on the screen.
If the actual text is longer it will be overwritten by the entry widget. It the actual text is
shorter than NAME W: the entry widget will nevertheless keep space for the defined width.
Therefor with this attribute the widgets can be aligned.
The default value is define by the common attribute NAME W which by itself has a default
value of 16 units.
• TABS:
This attribute is used only for folder widgets. It defines the names of all tabs and is a
mandatory attribute. The names are separated by the pipe character |. Blanks and tabs just
before and behind the | sign are ignored, but the tab names can include blanks. For example
# GUI _FOLDER_, TABS: global parameters | spectra parameters | image parameters
• DOL:
This attribute is used for parameters which expect a DOL instead of a string or a filename.
It is the exception of all attributes and is valid without specified value. But if a value is
define like DOL:1, than this number is used as HDU position and automatically added to
the selected file name. If no value is define like DOL:, than after a file is selected the GUI
reads all data structures in the selected FITS file. The user has to select in a list box a HDU
- name which is added to the selected file name.
• DISABLE:
With this attribute widgets can be disabled depending on the status of a check box widget
or depending on the selected item in a combo box widget. The value string of this widget
has a specific syntax:
#
#
#
#
#
#
example for combo box

example for check box
GUI param_name3, DISABLE:
GUI param_name4, DISABLE:
depend_on= image
depend_on= image | timing
depend_on1 = yes
depend_on1 = no
depend on is the parameter name (not the attribute NAME:) of an other widget. This has
to be either a check box widget or a combo box widget! If in the example above timing in
the combo box depend on is selected than the widget for param name will be enables while
the widget for param name2 will be disabled.
If disable depends on a check box widget the name behind the = sign has to be either yes or
no! Any other string will be ignored.
It is not possible to define a dependency from two different widgets for one parameter. The
GADC – param guiUsers Manual – Issue 1.1
5
second definition will overwrite the previous one.
By default a widget does not depend on the state of any other widget and is enabled all the
time.
4.3.1
Common Attributes
Common attributes are used to define default values. These default values are applied for all
parameters which are located behind the modification comment line of the common attribute in
the parameter file. It is possible to reset the default values several times in a parameter file.
The identifier for common attributes is COMMON for example:
# GUI _COMMON_,
NAME_W: 25, TEXT_W: 80
• NAME W:
Defines the default value for the NAME W attribute of each individual widget.
The default value for this common attribute is 16 units.
• TEXT W:
Defines the default value for the width of a text entry widget when it is created for a string
parameter (s).
The default value for this common attribute is 31 units.
• FILE W:
Defines the default value for the width of a text entry widget when it is created for a file
parameter (f).
The default value for this common attribute is 81 units.

for these parameters with the exception of the ”advanced” - button.
The second window is an example showing all group widgets and a more user friendly GUI. Attributes are defined for each widget to define the size and the
position. Selecting an entry in the ”enable” combo box enables and disables the widgets located in the frames.

Application Interface
The libparam gui.a library includes the class ParamGui which can be used by applications to
open a GUI with all its parameters and to get the values of the parameters defined by the user:
class ParamGui
{
public:
ParamGui(int argc, char ** argv);
bool
int
Quit();
Error();
bool
int
double
const char *
GetBool(const char * paraName);
GetInt(const char * paraName);
GetReal(const char * paraName);
GetString(const char * paraName);
};
GADC – param guiUsers Manual – Issue 1.1
10
The file param api.h has to be included to be able to use this class.
The constructor opens the GUI of the program and does not return until the user pressed the
Quit or the Run button of the GUI. The Quit() method returns true if the user pressed the Quit
button and returns false if the user pressed the Run button. If the user pressed the Run button
(Quit() returned false) the application can asked for the values of the parameters with the Get*()
- methods. The GetString() - method should be used for strings and file - parameters.
The method Error() should return 0 to indicate that no error occurred.
-1: the parameter file could not be opened.
-2: the requested parameter of one of the Get*() - methods does not exist.
-30xx: a PIL error. See PIL user manual.
Following example demonstrates the use of this class:
#include "param_api.h"
main(int argc, char ** argv)
{
ParamGui gui(argc, argv);
// opens the GUI
if (gui.Error() != 0)
{
printf("Error: %d\n", gui.Error());
return -1;
}
if (gui.Quit())
return 0;
// the user pressed the Quit button
// we can ask for the values of the parameters

printf("int: %d real: %12.4f
string: %s
ii, dd, str, bb);
bool : %d\n",
}

Errors and Warnings
• Selected files does not has any HDU or is no FITS file!
If the DOL: attribute is defined without a DOL-value the GUI reads all HDU - names after
a file is selected by the user. This error message appears if no HDU can be opened with a
DAL function.
• Environment variable ISDC ENV is not defined
Cannot find the help file!
When the user pressed the Help - button the GUI tries to find the help file of the corresponding
script or executable in the ${ISDC ENV}/help directory.
• File filename is missing.
Cannot display help text.
GADC – param guiUsers Manual – Issue 1.1
11
The environment variable ISDC ENV is set but the help text of the script of executable is
not available in the directory ${ISDC ENV}/help
• Cannot open file
filename
Cannot display help text
The help text is available in the ${ISDC ENV}/help directory, but the system call to open
the file failed. Check the read permission of the help file.
