+ \class LightApp_ModuleDlg
+ \brief A dialog box allowing to select study operation to be performed
+ on the module activating.
+
+ The dialog box is shown when the user tries to activate any module
+ while there is no opened study. The dialog box proposes user to select
+ one of the possible operations which should be done before module activating,
+ for example, create new study or open study from the file.
+ The available operations are assigned by adding the buttons with the unique
+ identifier to the dialog box. When the user clicks any operation button,
+ the dialog box sets its identifier as the return code and closes.
+
+ The typical usage of the dialog box:
+ \code
+ LightApp_ModuleDlg dlg( desktop() );
+ dlg.addButton( "New study", NewStudyId );
+ dlg.addButton( "Open study...", OpenStudyId );
+ int ret = dlg.exec();
+ switch( ret ) {
+ case NewStudyId:
+ // create new study
+ createNewStudy();
+ break;
+ case OpenStudyId:
+ // open study from the file
+ // ... show dialog box to choose the file
+ QString fileName = QFileDialog::getOpenFileName( desktop(), "Open File" );
+ if ( !fileName.isEmpty() )
+ openStudy( fileName );
+ break;
+ default:
+ // operation is cancelled
+ break;
+ }
+ \endcode
