nanogui: Thread: Problem with nano-x: scrolling pixmap through window (pixmap width > window width) will cut string

Hi all,

 

I have a problem with scrolling pixmaps.


I want to scroll an individual string text through a window with a
pixmap.
The pixmap has the dimensions following dimensions => 

width = stringlen in px, and the height of the display window

My display window has the dimension 800x140.

 

Now I want to write the string via GrText in the pixmap.

The problem is, that my text will cut after 800 px. 

Is the text string smaller than 800 px it works.

Could it be that the pixmap is restricted by screen width? How can I fix
it or do anyone know a workaround.

 

The scrolling itself works, only the cut of the text string is the
problem.

 

Many thanks.

 

Andi

Andreas,

What exact code are you using to create the pixmap?

Also what version of nano-X/mwin are you using.

You must use the function that specifies a pixel count that is large enough
for your text string. Do not specify a parent window, or that
window will be used for the default clip region. It sounds like
your pixmap is either being created the wrong size, or it is being
assigned a clip region that is based on a physical window, which will
then clip to screen boundaries.

Regards,

Greg
