296695 - Make dialog boxes change with DPI

Status: NEW

(SeaMonkey :: UI Design, defect)

Description

[Ian Neal]

This is spun off from bug 293427.
Quoting from jag:
Is the problem that though the font and dialog size changes with the DPI, the
images (e.g. checkbox, radio button) and such don't, causing the over flow?

Is there a generic solution to this?

The simplest solution seems to be to make the dialog height something like
LINE_COUNT * max(fontHeight96DPI, fontHeightCurrentDPI) where LINE_COUNT is
experimentally determined (looks like 25, give or take).

Can we make the width a certain amount of em, and the height "fit-to-content"?

Just brain storming here.

I don't seem to be able to test this with my Linux GTK2 build (currently Build
ID 2005053016). After changing the DPI setting in the prefs, Felix' DPI testcase
attachment 183394 [details] changes the DPI display and I see that the graphic has
a different size, but the dialog stays exactly the same AFAICT.

How do FF and TB get along without directly specifying the Options dialog height
for Unix and Mac? prefWindow.styleUnix only contains a width... If I just delete
the height from Seamonkey's prefWindow.size, I of course get a much too small
window.
