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
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
case 3 YComboBox * cc = YUI::widgetFactory(dialog,"SELECT",false); cc->addItem("XYZ"); cc->addItem("Blah"); cc->setValue("Blah");
I get a YUI::Exception
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?
For setting a ComboBox value please have a look at YCPPropertyHandler::trySetComboBoxValue() in http://svn.opensuse.org/svn/yast/trunk/ycp-ui- bindings/src/YCPPropertyHandler.cc Concerning your second question it might make sense to move the line that retrieves event into the loop. Hope that helps. Please feel free to ask if you have further questions.
