Hi
I am trying a few things in libYUI to ask of
1. How to set a value in a ComboBox? I have tried with both editable and non-editable comboBoxes
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
