Eloquence A.05.00 Release Notes
Eloquence A.05.00 Release Notes
Defaults File
The defaults file is used to provide defaults to dynamic created objects
and will be used by the cvdlg utility program to convert dialog files.
In addition it controls the dynamic behavior of the dialog server.
This chapter will shortly introduce each major element of the
Eloquence defaults file.
Please refer to the ISA Dialog Manager documentation for further
reference.
Callback Functions
The callback functions are used by Eloquence to filter unexpected events.
If an unexpected event is recognized, it will be ignored.
All further processing is done through the appropriate rules.
Eloquence needs the functions below to keep track of the current
object state.
| Function name | Gets called |
|---|
| EqPushButtonCB | if a pushbutton gets selected |
| EqCheckBoxCB | if a checkbox is (de-) activated |
| EqRadioButtonCB | if a radiobutton is activated |
| EqEditTextCB | if a edittext looses focus |
Returning from DLG DO
Returning from DLG DO statement is achieved by calling the procedure
EqExitEventLoop. It will return control back to Eloquence with a
given return code and an object path.
| Function name | Description |
|---|
| EqExitEventLoop | This will terminate DLG DO statement |
| | with given object and rule value. |
function void EqExitEventLoop( object, integer )
Help Subsystem
The help subsystem is used to call native platform help subsystem on a
help event. This is either VUE help or MS Windows help.
Both need the name of a help file specified by the Variable EqHelpVolume.
For example:
config variable string EqHelpVolume := "Help4Help";
The following functions are supported:
| Function name | Description |
|---|
| EqHelpOnObject | show object help |
| EqHelpOnTag | display arbitrary help |
config variable string EqHelpVolume;
function boolean EqHelpOnObject(object input);
function boolean EqHelpOnTag(object input, string input);
Resources
Resources are platform dependent.
Variant resources allow to have the same dialog source file for all platforms.
Whenever there are resource variants, they are used in the following manner:
| Variant | Platform |
|---|
| 0 | Motif GUI |
| 1 | MS Windows GUI |
| 2 | Alpha Windows |
To activate the appropriate resource variant, you have to specify
it on the driver commandline.
For example
-IDMfont 1 -IDMcolor 1
This will startup Dialog Manager with font and color resources variant 1.
Please refer to ISA Dialog Manager documentation for further reference.
The following font resources are allocated by default:
- BaseFont is used to calculate all sizes and positions.
BaseFont should be a fixed space font.
- NormalFont is used to display all text fields
Attributes
There are some user defined attributes allocated for use by Eloquence.
- integer EqRule
This is used to emulate the Eloquence .rule attribute.
- integer EqActiveline
This is used to emulate the Eloquence .activeline attribute.
- integer EqKbRule[10]
This is used to emulate the Eloquence function key handling
Popup Box
The popup box is mapped by the window EqPopup and it's associated
rules.
It will be reconfigured dynamically by Eloquence according to the needs
of a POPUP BOX statement.
Rules
- rule boolean EqSaveDialog( string Fname )
This is used by the cvdlg utility
- on CHECKBOX activate, deactivate
This is used to map CHECKBOX behaviour
- on RADIOBUTTON activate
This is used to map RADIOBUTTON behaviour
- on LISTBOX dbselect,
This is used to map LISTBOX behaviour
- on LISTBOX key EqKbSelect
This is used to map LISTBOX behaviour
- on EDITTEXT deselect
This is used to map EDITTEXT behaviour
- on dialog key EqKbF1 ... on dialog key EqKbF8
This is used to map Eloquence function key handling
