gmenu2x/src/linkapp.cpp
Maarten ter Huurne 88a4d1d911 Minor cleanups in Selector
Removed unused data member selRow.
Keep reference to LinkApp instead of pointer.
Call LinkApp::getSelectorBrowser once and store result.
Renamed fontheight to fontHeight.
Use iY consistently: store the item's y-coordinate in it.
