Hello,
I have another problem which is how to change the state of a
checkbox to "Partially Checked".
Explanation:
The user select a column. Each data in this column can be TRUE or FALSE. So
if a column contain only TRUE rows, then a checkbox should be "Checked", if
it contains only FALSE then it should be "Unchecked" and finally if there is
a mix of TRUE and FALSE the checkbox should be "Partialy Checked".
I've seen that behaviour under a few application, where when it was checked,
there was a black V drawn on the button of the checkbox, when unchecked the
V was cleared, and when partially cheked, the V was grey-ish.
I've tryed using the fg fields of the Style of the checkbox, but it had
no effect! It seems that Gtk is using a picture to draw the checkbox. How
can I do it?
Thank you for any help,
Best regards,
---
