Re: [C++] Check if mouse on the GUI
What do you mean for all elements at once?
If you want to be notified when an element on a subtree of elements is hovered with the mouse you just need to register to MouseEnter in the parent of that tree, because routed events traverse all elements in the tree.
To check if mouse is over any element of the GUI you can use VisualTreeHelper like this:

Code: Select all
Visual* root = VisualTreeHelper::GetRoot(anyElement);
HitTestResult hit = VisualTreeHelper::HitTest(root, mousePos);
if (hit.visualHit != 0)
{
// Mouse is over a GUI element
}
else
{
// No GUI element is under the mouse

I have GUI but it's not only one who capture mouse click events. My scene capture it too and I want every click on GUI not be captured with scene.
