[8.0ß-x64] LB_GETTEXT* stopped working for file panels

Flint · Post by *Flint » 2011-10-02, 22:43 UTC

When I try to send LB_GETTEXTLEN or LB_GETTEXT messages to TC's file panels in x64 version I receive the length equal to zero for each element (and empty string as its contents).

In TC x32 these messages work correctly.

Unfortunately Lazarus blocks all Windows messages below WM_USER from getting through to the program, for cross platform compatibility. the only way to access them is to subclass the windows and try to handle the messages from there. This is a lot of work, and I have already added it for various functions...

Could you please do it for file panels too, or provide some other method of getting the file names? The problem is that all multi-file editor redirectors (like ChoiceEditor, OSFTC, F4Menu, etc.) need it to allow opening several selected files by pressing F4.

Yes, I will of course try to add it again, I just didn't have the time yet.

IMO it would be better to provide something like an official scripting api.
Currently there are several workarounds needed to get some of the informations.

Methods like this would be great:
getFolder(left, right, source, target), getFiles, getSelectedFiles, sendCommand, sendCustomCommand, setFolder, setFileSelection, etc.

OK, thank you. I'll be waiting patiently.

Fixed in 8.0β4. Thanks!
Now I can adapt my TCER to the x64 version.

Thanks for reporting it!
