问题
I installed qcachegrind on OS X via brew. No problems. I generated a few *.callgrind files and viewed them with qcachegrind. Again, no problem. While viewing one file I accidentally closed the "flat profile" dock panel. Now anytime I open qcachegrind that panel is missing.
I tried running lsof to figure out where qcachegrind was getting its preferences, but that didn't help. I deleted a file from ~/Library/Preferences/io.github.qcachegrind.plist that appeared to store window position data, but that still hasn't resolved the issue. This screenshot illustrates the problem; also note that there are no menus available to pull down either.
Someone else posted a similar query for kcachegrind that was answered here: How do I get back to the beginning in kcachegrind?
However, that solution doesn't work for OSX.
Anyone have a clue what file needs modification or deletion to restore default window behavior and position for qcachegrind?
回答1:
Right click anywhere on the top bar and select Flat Profile from the popup menu:
Update: clicking on the top bar of the sub-panes also works (in case you hide the Main Toolbar).
The Settings menu doesn't seem to be reachable on Mac OS X, and I couldn't find any mention of ~/.kde/share/config/kcachegrindrc on my hard drive for rm.
