Switching between decimal and hex watch-display

[rgruber at users.sourceforge.net]

Hello,

I\'ve done a lot of debugging last week and I was very confused about the fact that KDevelop still has no possibility to switch between decimal and hex watch-display. So I\'ve decided to hack a bit and here it is!

I\'ve added an entry to the popup menu which opens if you righ-click a variable that is already in the watch-list. Everytime you select that entry, the selected watch toggles between no formating and hex-value formating. The converting is done by adding \"/x\" infront of the variablename. I\'ve tested it pretty hard and for me it workes very well.

If you\'re interested in adding this to KDevelop, you can download variablewidget.[cpp,h] from http://kmp3indexer.sf.net/misc/ or alternatively I\'ve appended the cvs diffs for the two files.

Best regards,
Robert Gruber

BTW: This will close the bug #60670 from bugs.kde.org
