问题 I am having trouble to extract text from textarea using WPF code behind. Example: Sunny day in London if the cursor is set on [d*ay] it should return day. * for the cursor.

问题 I'm changing the caret size using - (void)drawInsertionPointInRect:(NSRect)aRect color:(NSColor *)aColor turnedOn:(BOOL)flag .
