It is the scaling (getXScale / getYScale) indeed. I've got tslib working with Gnash now. I'll post the patches shortly.

Looking at the other GUI code, I think I know where I got it wrong. The coordinates are always scaled using getXScale and getYScale. I didn't implement that. The scale seems to depend on the size of the movie. I'll add the scaling to my code first thing in the morning and report the results. I'll be back...

I'm working on getting tslib (generic touchscreen driver/filter) to work with fb-gnash on an embedded device. I noticed I have to click outside buttons to activate them.

I tried the following flash file:

# gnash -v -vb t.log http://www.permadi.com/tutorial/flashperl/helloperl.swf

It shows a button and a text. When the button is clicked, the text changes. On the embedded device, the button is in the center of the screen.

When I click the center of the button there is no response. The touchscreen calls notify_mouse_move with the following coordinates (width and height are m_stage_width and m_stage_height):

196] 07:24:03: DEBUG: Touched x: 155 y: 120 width: 320 height: 234
1196] 07:24:03: DEBUG: lifted x: 155 y: 120

However, when I click above the button, the button is activated.

1169] 07:14:43: DEBUG: Touched x: 159 y: 83 width: 320 height: 234
1169] 07:14:43: DEBUG: lifted x: 159 y: 83
1182] 07:14:43: DEBUG: HTTP response 200 from url http://www.permadi.com/cgi-bin

Another example from the same page has the same problem. I have to click above the button to activate it.

Yet another flash file:
In this flash file I have to click slightly below the buttons to activate them. I cannot click the return button to restart the animation.

I tried fltk-gnash under windows. The first and third file work okay. I also tried gtk-gnash (using tinyx and tslib) on my embedded system. In this case the buttons also work okay.

Any ideas?
