Unlike FoxPro or MFC there doesn't seem to be any automagic support for the
standard edit commands in a main menu. The textbox does have a context menu,
but there doesn't seem to be a way to associate that with a main menu or a
merge menu (in MDI).
I have an idea for a method that might work:
------>
bool AllowCut()
{
TextBox textBox = GetCurrentControlAsTextBox();
if(textBox == null) return false;
// Do we have text to cut?
return textBox.SelectionLength > 0;
}
void CutText()
{
TextBox textBox = GetCurrentControlAsTextBox();
if(textBox == null) return;
// Cut the text
if(textBox.SelectionLength <= 0) return;
Clipboard.SetDataObject(textBox.SelectedText);
textBox.SelectedText = "";
}
// Return active control if it is a textbox, otherwise null
TextBox GetCurrentControlAsTextBox()
{
Form activeWin = ActiveMdiChild;
if(activeWin == null) return null;
Control activeControl = activeWin.ActiveControl;
if(activeControl == null) return null;
return activeControl as TextBox;
}
<------
These routines would be wired into a main MDI window.
This code has _NOT_ been tested and might not work, but it is where I will
start. Better ideas are welcome!
