Longtime ruby user for writing scripts, never thought I would use it for a program with a GUI. Love it!
I created a GUI and used the print widget, but the size of the GUI on the print out is tiny. Checked your samples and they also printed tiny (unreadable). Is there a setting that would fix that, or something wrong with my set up? I am using Windows 11.
Thank you.
Ricardo, I am sorry I didn't see your comment till now (May 2, 2024). It is normally better to reach me on the Glimmer Gitter chat if you have support questions related to Glimmer GUI libraries.
There are 2 ways to print, the built-in automatic way, which assumes everything fits on one page (I assume that is the one you tried), and the custom manual way, which gives you more control over how you size things.
The automatic way is demonstrated in Hello, Print!:
Hello, Print! code
The custom way is demonstrated in Hello, Print Dialog!:
Hello, Print Dialog! code
To customize things the manual way, you have to study the SWT Printer class:
Printer API
And, SWT PrintDialog class:
PrintDialog API
As well as any other related classes like GC:
GC API
And, Image:
Image API
You would have to tweak the code in Hello, Print Dialog! to fit your needs.
For example, GC, has 2 drawImage methods, one that draws an image as is, and another that scales the image as it is drawing it. It is possible that you need to use the 2nd version (as seen in the GC API page linked above) to scale the printout of what you are printing.
Hit me up on the Glimmer Gitter chat if you have any further questions.
