1. Matt! I need help making a wxEuphoria add-on library

I stumbled across this post: How to Draw Gradient Buttons and figured it would make a nice addition to wxEuphoria. But I didn't want to just embed the code into the library. Instead, I figured I could build it as an add-on by making my own DLL and wrapper. I've got just about everything done, most of the code is written, the DLL compiles nicely with Watcom, and my new wxGradientButtons display perfectly.

Except, when I assign an event handler for wxEVT_COMMAND_BUTTON_CLICKED, the program crashes with a machine exception when I click the button, and I can't figure out why. All the "button" (which is really a wxWindow) does is create a new event and push it to the event stack, which seems pretty simple. I'm so close on this, I can practically taste it.

void wxGradientButton::OnLeftUp( wxMouseEvent& event ) 
{ 
	if(GetCapture() == this) 
	{ 
		ReleaseMouse(); 
		Refresh(); 
		if ( GetClientRect().Contains(event.GetPosition()) ) 
		{ 
			wxCommandEvent evt(wxEVT_COMMAND_BUTTON_CLICKED, GetId()); 
			GetEventHandler()->AddPendingEvent(evt); 
		} 
	} 
} 

Note: You'll have to adjust the WXEUDIR path in the make.bat file to your own wxEuphoria trunk.

I knew it would be something simple! And only one line of code at that... thanks for fixing it!

I do not have a bitbucket account. I would be interested though...
