This example demonstrates how to create an extension dialog.
Essentially all that is necessary is to create a standard dialog and then create a TQWidget form to be used as the extension. See the article in TQt Quarterly issue #3.
Project file:
TEMPLATE = app LANGUAGE = C++ CONFIG += qt warn_on release RETQUIRES = full-config nocrosscompiler SOURCES += main.cpp FORMS = mainform.ui \ dialogform.ui \ extension.ui DBFILE = extension.db
Implementation:
/**************************************************************************** ** ui.h extension file, included from the uic-generated form implementation. ** ** If you wish to add, delete or rename functions use TQt Designer which will ** update this file, preserving your code. Create an init() function in place ** of a constructor, and a destroy() function in place of a destructor. *****************************************************************************/ #include "dialogform.h" #include "extension.h" #include <qapplication.h> #include <qcheckbox.h> #include <qlineedit.h> void MainForm::init() { sessions = FALSE; logging = FALSE; log_filename = TQString::null; log_errors = TRUE; log_actions = TRUE; } void MainForm::optionsDlg() { DialogForm *dlg = new DialogForm( this, "dialog", TRUE ); Extension *ext = (Extension*)dlg->extension()->qt_cast( "Extension" ); if ( !ext ) return; dlg->sessionsCheckBox->setChecked( sessions ); dlg->loggingCheckBox->setChecked( logging ); ext->logfileLineEdit->setText( log_filename ); ext->logErrorsCheckBox->setChecked( log_errors ); if ( dlg->exec() ) { sessions = dlg->sessionsCheckBox->isChecked(); logging = dlg->loggingCheckBox->isChecked(); log_filename = ext->logfileLineEdit->text(); log_errors = ext->logErrorsCheckBox->isChecked(); } } void MainForm::tquit() { TQApplication::exit( 0 ); }

"<<<" : ">>>" ); detailsPushButton->setText( text ); }

Main:
#include <qapplication.h> #include "mainform.h" int main( int argc, char ** argv ) { TQApplication a( argc, argv ); MainForm *w = new MainForm; w->show(); a.connect( &a, SIGNAL( lastWindowClosed() ), w, SLOT( tquit() ) ); return a.exec(); }
