I am running cefsharp/75. I want to turn on zooming with the ctrl key and the mousewheel. My event handler is never triggered. And if you hold ctrl and use the mouse will the screen doesn't move. So something inside the control and handling the event. Is there just a setting I am missing?
I added mouse and keyboard zoom. In init section subscribe for events
cefBrowser.PreviewMouseWheel += CefBrowser_PreviewMouseWheel;
cefBrowser.KeyUp += CefBrowser_KeyUp;
I used PreviewMouseWheel
to avoid scrolling during zoom ( e.Handled = true
).
private void CefBrowser_PreviewMouseWheel(object sender, MouseWheelEventArgs e) {
if (Keyboard.Modifiers != ModifierKeys.Control)
return;
if (e.Delta > 0)
cefBrowser.ZoomInCommand.Execute(null);
else
cefBrowser.ZoomOutCommand.Execute(null);
e.Handled = true;
}
private void CefBrowser_KeyUp(object sender, KeyEventArgs e) {
if (Keyboard.Modifiers != ModifierKeys.Control)
return;
if (e.Key == Key.Add)
cefBrowser.ZoomInCommand.Execute(null);
if (e.Key == Key.Subtract)
cefBrowser.ZoomOutCommand.Execute(null);
if (e.Key == Key.NumPad0)
cefBrowser.ZoomLevel = 0;
}
So now cef zooming almost like chrome
