Pritpal, thanks
I need a basic code sample to test hbqt, without use of QInputContext,
QWidget, just to know if hbqt-qt461 for OS/2 will run
Something as minidemoqt.prg :-)
This is not possible without QWidget class.
QWidget is the parent of all GUI classes.
This is the object tree :
QObject, QPaintDevice
QWidget
All Other GUI Widgets - menus, buttons, etc
So I need to resolve it in base class first,
then probably everything will built properly.
Please do the following:
0. QApplication.cpp -> HB_FUNC( QT_QWIDGET_INPUTCONTEXT )
Comment it out.
Done
1. QWidget.cpp -> HB_FUNC( QT_QWIDGET_INPUTCONTEXT )
Comment it out.
Done
2. Also commentout corresponding methods in
TQApplication and TQWidget.
Done
3. Drop QInputContext.cpp and TQInputContext.prg from filelist.mk
Done
Compile hbQT. Do it compiles then ? If yes, we have the solution
already,
Compiling hbqtgui fail with QWidget.cpp, as expected, with:
----------------------
gcc -I. -I../../../../../../include -Zomf -Wall -W -O3
-DHB_LEGACY_TYPES_OFF -IE:\qt4\include -IE:\qt4\include/QtCore
-IE:\qt4\include/QtGui -DHB_FM_STATISTICS_OFF -oQWidget.o -c
../../../QWidget.cpp
../../../QWidget.cpp: In function 'void
HB_FUN_QT_QWIDGET_ACCESSIBLEDESCRIPTION()':
../../../QWidget.cpp:196: error: 'class QWidget' has no member named
'accessibleDescription'
../../../QWidget.cpp: In function 'void HB_FUN_QT_QWIDGET_ACCESSIBLENAME()':

../../../QWidget.cpp:976: error: 'class QWidget' has no member named

make[1]: *** [QWidget.o] Error 1
----------------------
So I used:
QWidget.cpp
===========
/*DAVID:
HB_FUNC( QT_QWIDGET_ACCESSIBLEDESCRIPTION )
{
hb_retc( hbqt_par_QWidget( 1
)->accessibleDescription().toAscii().data() );
}
*/
/*DAVID:
HB_FUNC( QT_QWIDGET_ACCESSIBLENAME )
{
hb_retc( hbqt_par_QWidget( 1 )->accessibleName().toAscii().data() );
}
*/
/*DAVID:
HB_FUNC( QT_QWIDGET_SETACCESSIBLEDESCRIPTION )
{
hbqt_par_QWidget( 1 )->setAccessibleDescription( QWidget::tr(
hb_parc( 2 ) ) );
}
*/
/*DAVID:
HB_FUNC( QT_QWIDGET_SETACCESSIBLENAME )
{
hbqt_par_QWidget( 1 )->setAccessibleName( QWidget::tr( hb_parc( 2 ) ) );
}
*/
TQWidget.prg
===========
//DAVID: METHOD accessibleDescription()
//DAVID: METHOD accessibleName()
//DAVID: METHOD setAccessibleDescription( cDescription )
//DAVID: METHOD setAccessibleName( cName )
/*DAVID:
METHOD QWidget:accessibleDescription()
RETURN Qt_QWidget_accessibleDescription( ::pPtr )
*/
/*DAVID:
METHOD QWidget:accessibleName()
RETURN Qt_QWidget_accessibleName( ::pPtr )
*/
/*DAVID:
METHOD QWidget:setAccessibleDescription( cDescription )
RETURN Qt_QWidget_setAccessibleDescription( ::pPtr, cDescription )
*/
/*DAVID:
METHOD QWidget:setAccessibleName( cName )
RETURN Qt_QWidget_setAccessibleName( ::pPtr, cName )
*/
and hbqtgui.lib build entirely
link demos. Those must then link properly.
If all goes fine, I will drop QInputContext alltogether.
Without above exercise, it is difficult to isolate other matters.
Logs of demos are useless as QWidget is not linked and all other
Qt world resolves around it.
So you can:
- drop QInputContext alltogether.
- Guard *Accessible* methods for OS/2 and
#ifndef QT_NO_ACCESSIBILITY / #endif
while "dummy QAccessible implementation in 4.6.1" can be completed
Trying to use hbqt* libs with samples/projects:

hbide project ( the BIG one ! )
===============================
- Build fine
- Open a window with content, with a lot of icons, menus, ...
- Windows resize, max, min, move, ... work fine
- Many checkboxs, actions work fine
- Many actions fails, for example "Open"

So we have our firsts Harbour+os2gcc442+hbqt+qt461 applications running,
but with failures still
We are advancing :-)
