Shows tooltip(the center black box), zero crosshairs, and some icon buttons.

When in Windows (I haven't been able to try this in Linux), I use a high
contrast black theme to help with my visual disability.  Some of the display
items in Dia are hardcoded with a black/dark foreground and are hard or
impossible to see with a high contrast black color scheme.  Some of the items
that are affected by this are:

- Tooltips (I think all of them!)
- Line end styles in the list boxes
- Some of the Icon buttons on the left sidebar are hard to make out.
- Text box tool (when editing text, the background is yellow...white text on
yellow background is hard to see.
- The Zero Crosshairs are hard to see.  (dark on dark)

Because of these problems, Dia is very difficult to use for people with my eye
condition.  I am going to attach some screen shots of some occurrences.

Thanks,
Zane

The behavior is not better on Linux (there already is bug #377413 about invisible icons with black as background color).

 - Tooltips: I think there is something wrong with the gtk theme you are using,
   Dia does not manipulate tooltip colors
 - Line end styles: this was a bug which even made the line selector and the
   arrow selector use different colors. It is fixed in my local version.
 - Icons: this might require the most effort becuase there are more than 600 
   icons distributed with Dia. I've played a bit with an algorithm to improve
   them, but I'm uncertain if that would improve the situation for you.
   (example toolbox screenshot follows)
 - Texttool: the text highlighting should probably be changed to use the theme
   colors for selected text - foreground and background
 - "Zero Crosshair": I simply don't understand;)

BTW: if only "some" icons are concerned it might be better to adjust these, maybe by drawing a white outline around the black one?
Comment 5 Zane 2009-10-25 10:39:22 UTC
Thanks for considering my problems!  

- I am using what I think is the standard gtk+ theme (wimp?) for Windows.  After looking at some other applications (I don't use many gtk apps on windows) I now think you are right.

- I don't know if you mean the lines end styles were fixed before I sent this message or if you fixed them now and it will become effective in the next binary.  I did see in the screenshot you provided that they looked fine :).

- Your algorithm makes the icons much more visible for me (from your screenshot).

- Your Text tool idea sounds like the best approach.

- Sorry, I guess I could have explained what I meant about the zero crosshairs a little more, my appologies.  I am referring to the (blue? purple?...can't tell) lines that indicate the horizontal and verticle zero marks on the grid.  They are dark blue-ish on black.  Perhaps: an option to change this color / style / thickness / etc?

I appreciate your help!
Zane

I fixed the arrow-selector themeability just after your report. The fix will be part of the the upcoming dia-0.97. The other things need some more thinking and changes. I hope they'll be addressed for dia-0-98, whenever that's released ;-)
