I am learning to design a GUI in GWT
I have RootPanel where i have put all the widgets.
In one panel i have put tree Widget where the treeItems are added on the success of RPC call on the selectionHandler
What I want to do:
When click on treemItem , All the other treeItem and the widgets on the same and different panel should not be selected. Like there is a processing going on so no other things are allowed to do.
Please suggest some idea or sample code or example.
If I correctly understand you, you want to disable user clicking some widgets until specific callback finishes. In order to do that you should have a custom panel with bigger
z-indexandopacity. For example, something likeDialogBox‘ssetGlassEnabled(true)method and try using that technique in your callbacks. When asynchronous request starts show that panel inonSuccessandonFailureyou should hide it. By the way, my-gwt has LoadingPanel class which implements such feature. And also another mask live demo in GWT-Ext.
