Unfortunately, we are yet unable to repro the problem. Could you please:

1. Paste us, the exact XAML you are using.
2. Try using that XAML in the minimal sample (the TUX one) included in the LeadWerks wrappers.

If these steps don't help with the problem we will probably need to debug your application to find the problem.

Sure. Here's the XAML. It's commented so you have a better idea of what does what. The buttons I'm trying to add at run time get added to the "_pageNAV" canvas...

I think I know what the problem is... as suspected there are UI elements over the canvas named _pageNAV.

You have a Border named _CURSOR that I suppose is moved together with the mouse, that is placed over all the other elements. If you don't want that this element captures mouse events, you can set the IsHitTestVisible property to false:
Code: Select all
<Border x:Name="_CURSOR" Width="15" Height="15" Canvas.Left="0" Canvas.Top="0" Margin="5,0" BorderBrush="Black" BorderThickness="0" IsHitTestVisible="False"> ...
Let me know if this fixes your problems.

Sorry, but that did not fix the problem. I even tried adding it to both the Border (as you suggested) and the child rectangle that displays the cursor image. :( I would think, too, that if this were the problem it would also affect the "Upper mode selector buttons", which are also created before the cursor.

Again, buttons created on the main canvas (both in XAML and dynamically) do work fine. It's only the ones on the sub-canvas that do not. At this point, as a work-around until this is sorted out, I'll probably put each page in a separate XAML, and just update/display the appropriate one as needed...

Thank you for the continued assistance though...

Hi Michael,

Could you please disable the code that updates the _CURSOR, or even better, eliminate the _CURSOR element from the XAML and verify is the problem is still there.

Thanks!

Done (tried both)--no help. The problem is still there. Sorry...

Next step. I need you to send me a zip with a XAML and all dependencies needed (images, fonts) that works as expected in XamlPlayer but doesn't work in your engine. This XAML must fail without having to do anything in code.

Let's see if with that we can advance...

Check your email. I sent a .rar with both the XAML and the 1 required atlas .png

Hi,

Could you verify that buttons placed inside the _pageNAV don't react to the Click event?
Attach an event handler to the Click event and see if the handler is called (although the visual representation of the button doesn't changes).

We found a problem with the default style that doesn't changes visual representation of the Button on mouse over/press if the Button has a Background/BorderBrush set (overriding style default brush).

Re: Creating a button dynamically (C++)

Posted: 29 Aug 2014, 20:46
by Michael_J
Verified -- any button placed in _pageNAV (either in the XAML or at runtime) has no reaction to the click event. The click event is never called...
