Oops, we just noticed that's the wrong file. We cut the line

int64 data;

from Drawing_en-us.tpp and paste it to the very end of Draw_en-us.tpp. Go back to Draw.h, line 45, right click the dark blue square again, select "copy code reference id".

Switch back to Draw_en-us.tpp, with caret on the newly pasted line, Ctrl-M to bring out the "code reference" dialog. Paste the code reference id we just copied, which should be "Upp::Font::data". Click OK to close the dialog.

So far so good. Click Draw.h tab to bring it current. Oops, an "Invalid memory access!" occurs. If it doesn't, move mouse to over the blue square beside line 45 to show a help content. It happened to me twice, verified.

This error can be fixed in the following way. When restarting theide, you will be prompted to disable Assist features, select "Yes", go to the tpp file, delete thr problematic help line. Then use menu Setup/Settings, on Assist tab, check the first item "Assist libclang parser is enabled..." to reenable Assit++.
