Ruler can't handle any mouse event

I'm using the latest version of winform diagram. I'd like to do something when double-click on ruler. However seems most of events are ignored?

Hi,

Ruler is a composite control and you will have to attach handlers to its child controls to detect double click on the ruler scales:

Code
Select All
HandleDoubleClick(ruler);

void HandleDoubleClick(Control parent)
{
	if (parent is DiagramView || parent is ScrollBar)
		return;
	parent.DoubleClick += OnRulerDoubleClick;
	foreach (Control child in parent.Controls)
		HandleDoubleClick(child);
}

private void OnRulerDoubleClick(object sender, EventArgs e)
{
	MessageBox.Show("ruler double clicked");
}


I hope that helps,
Stoyan
