| − | '''Notes'''
| |
| − | * GetParaMetric() on Cocoa always returns True and says indent is 0. Its not possible to set an indent of more than zero so hard to know if its working or not. Follow the code David....
| |
| − | * SetParaMetric() on Cocoa makes no visible change to text. On Cocoa it calls TCocoaWSCustomRichMemo.SetParaMetric(..) which includes a line "txt:=view.textStorage" that seems to cause a ''silent and local crash'' (my words). The method is terminated prematurely dropping back to the RichMemo function and nothing is done to the text. This premature termination confuses gdb, crashing it with a message ''cannot find bounds of function''.
| |
| − | * Search() always returns false on Cocoa but does not set vars at all.
| |
| − | * For GetTextAttributes(), on Cocoa fails because GetTextLen() does not work. I think something like UYF8length(Text) seems to work, possibly slow. Wonder how much faster UTF8LengthFast() is ?
| |
| − | * GetStyleRange() is a problem elsewhere too, I have a local function to do that.
| |
| − | * I have a local SetRangeParams() working, might be slow, will appear when I've tested it a bit more....
