Are you having trouble enabling the use of keyboard shortcuts CTRL+A, CTRL+X, CTRL+C, CTRL+V to select all, cut, copy, or paste text within a wxWidgets MSW wxTextCtrl? At least in wxWidgets 3.0.0, there is a quick and dirty style configuration that can do this without having to declare or connect to any events: make your wxTextCtrl use the wxTE_RICH style (wxTE_AUTO_URL also does the trick, and the wxTextCtrl documentation refers to wxTE_RICH). Note that this little article was written without knowledge of whether this is the designed and intended behavior of wxTextCtrl. The wxWidgets 3.0.0 documentation does indicate: "The following commands are processed by default event handlers in wxTextCtrl: wxID_CUT, wxID_COPY, wxID_PASTE, wxID_UNDO, wxID_REDO. The associated UI update events are also processed automatically, when the control has the focus." So, if you have a wxTextCtrl that doesn't process select all/cut/copy/paste in the expected manner by default, but does so when wxTE_RICH is used, is this a bug? Maybe wxTE_RICH gives it focus somehow? In any case, the trade-off in using wxTE_RICH is, well, your control is now a rich-text control. Does this impact your application? Arguably in the majority of cases it won't :) If use of wxTE_RICH is confirmed as the intended style, then this post may be updated to reflect that in the future. Please leave a comment if you know the answer and preferably add a supporting URL!
