Also - I'm suspicious of: svx/source/tbxctrls/tbcontrl.cxx- else if ( ( rDCEvt.GetType() == DataChangedEventType::FONTS ) || svx/source/tbxctrls/tbcontrl.cxx: ( rDCEvt.GetType() == DataChangedEventType::DISPLAY ) ) I guess this is perhaps to handle things like font-hint changes on Linux (perhaps) - and I imagine that this particular font combo box is -very- expensive to setup & re-render. Might be nice to just use FONTS for that - and try to detect if any display settings affect font rendering - and emit a FONTS changed if they do (?) =) The: // HACK: Comparing is incomplete comment in lcl_GetDocFontList looks particularly interesting to investigate I guess =) if we can avoid re-building it I imagine life is far better.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
