http://doc.opensuse.org/projects/libyui/HEAD/classYComboBox.html says: In non-editable mode, a ComboBox works very much like a SelectionBox that uses fewer screen space. In that mode, it is recommended to use selectedItem() to retrieve its current value and selectItem() to set it. In editable mode, a ComboBox is more like an InputField with a list to pick predefined values from (for less typing). In that mode, it is recommended to use value() and setValue(). > > I have a > YComboBox * cc = YUI::widgetFactory(dialog,"SELECT",true); > cc->addItem("XYZ"); > cc->addItem("Blah"); > cc->setValue("Manu"); > > In this case, the value Manu is not set and highlighted > > Now lets take this case > YComboBox * cc = YUI::widgetFactory(dialog,"SELECT",true); > cc->addItem("XYZ"); > cc->addItem("Blah"); > cc->setValue("Blah"); > > Same thing blah is not highlighted I think both should work. > case 3 > YComboBox * cc = YUI::widgetFactory(dialog,"SELECT",false); > cc->addItem("XYZ"); > cc->addItem("Blah"); > cc->setValue("Blah"); > > I get a YUI::Exception That is as expected, for non-editable comboboxes selectItem should be used. > > So if anyone can cross check this case and let me know if it is a bug or not? > > Second Question is related to event handling > > If a selection in a comboBox changes, how would I able to recognise it > > Currently I follow this approach > YDialog * dialog = YUI::widgetFactory->createDialog(); > YComboBox * cc = YUI::widgetFactory(dialog,"SELECT",false); > YWidgetEvent * event = (YWidgetEvent*)dialog->waitForEvent(); > while(1){ > if(event->reason()==SelectionChanged){ > cout<<"XYZ"; > } > }; > > this does not seem to work ie the dialog is not recognising changes in > my combobox, how do I solve them? Maybe you need to set the boolean Notify property? http://doc.opensuse.org/projects/YaST/openSUSE11.3/tdg/AAA_All-Widgets.html http://svn.opensuse.org/viewvc/yast/trunk/libyui/src/YWidget.cc?revision=60778&view=markup#l418 Hmm, the @property tags in the source are not handled by any docs generator AFAICT. Prashanth, it would be good to enable that. -- Martin Vidner, YaST developer http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu
