selectionchanged

I have recently picked up Qt again, and started refreshing my memory. Creating a custom data model for a table was easy enough. Now I am trying to retrieve the selected data. Take note that I use custom data objects. Example of my custom model: platform.h class Platform { public: Platform(); Platform(QString name); QString getName(); void setName(QString name); private: QString m_name; }; Very simple data structure for testing purposes. I then implemented a QAbstractTableModel, the Data() method looks like this: platformmodel.cpp QVariant PlatformModel::data(const QModelIndex &index, int role)

I have list view control where on change of selection, I do check - if selected record count is greater then zero then only enable group box controls else keep it disable. Because, those are controls are related to selected record only. if no record selected then it should not be enable. Following is my listview's selected changed event: Private Sub lv_SelectedIndexChanged(sender As Object, e As EventArgs) Handles lv.SelectedIndexChanged If lv.SelectedItems.Count() > 0 Then ... . ResetifNorecordSelectedState(False) Else .. ResetifNorecordSelectedState(True) End If Problem: On each time when

Is it possible to use nsISelectionController to watch when a a highlight/selection is made? I know that there are different selection scopes. I want to watch when a user makes a selection in the default scope seen at MXR - nsISelectionController Constants . Kind of like an addEventListener on select change but on the text nodes of the document. Thanks Noitidart I found a solution but it doesn't use nsIController as @Neil had recommended in a SO topic HERE to look at viewSource.js. Im still interested in a nsIController solution if possible, im trying to understand that sucker it confuses me.

I have a tab control, and a few tab items. I am successfully listening to the SelectionChanged event, and checking if the tab I'm interested in is the currently selected one. I'm using this code (below), and stepping through the debugger, I can see that my branching logic works as designed; however, the issue I'm having is that something is overriding this call to txt.Focus() because after the correct tab item is displayed, the focus is not on the text box. private void tabMain_SelectionChanged(object sender, SelectionChangedEventArgs e) { // exact same behavior with and without this line e

The ListBox control does not implement a Command property. I have to attach some functionality to the SelectionChanged event. Somebody knows how can I do it? Please help me I prefer using a binding to the SelectedItem and implementing any functionality in the setting of the binding property. <ListBox ItemsSource="{Binding Items}" SelectedItem="{Binding SelectedItem}" /> ... public class ViewModel { public IEnumerable<Item> Items { get; set; } private Item selectedItem; public Item SelectedItem { get { return selectedItem; } set { if (selectedItem == value) return; selectedItem = value; // Do
