if you used the designer, just double click the zoom in button that it will create an event handler for the Click event in the code. Then just call your zoom in function there.
If you didn't use the designer, you'll need to attach the event handler yourself:
buttonZoomIn.Click += new System.EventHandler(buttonZoomIn_Click);
private void buttonZoomIn_Click(object sender, EventArgs e)
{
// call your zoom in function or insert the code to zoom in here
}
stir
use a timer then. In the mouse down event start the timer:
timer.Enabled = true;
m_buttonPressed = true;
then in the timer's tick function do the zoom:
private void timer_Tick(object sender, EventArgs e)
{
// set the interval
timer.Interval = m_repDelay;
if(m_buttonPressed)
{
// zoom
}
}
then in the mouse up event just stop the timer:
if(this.Enabled == false)
return;
timer.Enabled = false;
m_buttonPressed = false;
