overheard that they looked too ninety-ish. TODO: The code behind this is work in progress. The basic idea is to extract all drawing code into a new class BControlLook, of which there is a global instance be_control_look, instantiated in InterfaceDefs.cpp. At the moment, all the old drawing code is still there, and the usage of be_control_look is inside if-bodies checking the instance against NULL. In another words, by not instanitating be_control_look, you can revert back to the old look. BControlLook's job is to provide reusable methods for drawing certain types of frames, backgrounds and labels, so that application developers can make controls that re-use the same drawing code as built-in controls and adopt to changes made there. I have added the notion of "borders". Each of the frame drawing methods can be made to draw certain borders only, which is supposed to help when controls shall visually attach. This feature is not fully explored at all ATM. TODO: Update BColumnListView header view and BStringItem text spacing. Update other apps where it makes sense to use BControlLook. For the moment, only Tracker and LaunchBox are updated. More... NOTE: The new look is not very radically different, so that existing apps do not immediately look too ugly or out of place. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29221 a95241bf-73f2-0310-859d-f6bbb57e9c96
