Retrieving data from widgets
in [wxWindows]
|
From: Hans-J. Ude on 4 Aug 2010 07:01 I know that wxWidgets is a cross-platform system system. My question only refers to the windows implementation. I wrote a program which retieves data from other programs (www.wolptec.de) but it can't handle programs written with wxWidgets yet. Where in the documentation can I find out which messages are used for low level data exchange, especially with a kind of list control widget? TIA, Hans

I know you are one of the maintainers of the project and know it very well, but honestly, I doubt that. I don't actually know the implementation but a standard listview common control is of class 'SysListView32' and there is no such window around. The classname is 'wsWindowClassNR' as my program and others like Spy++ reveal. Like most other wx-windows too and when I send it a WM_GETTEXT message it responds with 'control'. Do you know a document where the internals are described? Something more detailed than the normal high-level usage. I need to know what happens under the hood. Thanks, Hans

If you use wxListCtrl, there is and Spy++ does reveal it. If you don't see it, you are either not using wxListCtrl or using its generic implementation which is not the default in standard wx build. > Do you know a document where the internals are described?
