Hi,
I'm using 3.1M5. Can anyone confirm if there any way to center a file
dialog in the middle of the parent shell. (This always opens in the top
left of the parent)
FileDialog dlg = new FileDialog(shell, SWT.OPEN);
....I saw this message already posted and wanted to confirm that this is
correct & also appies to the filedialog....
Many thanks for your time...
Paul

Hi Robert,
Thanks for the reply. I've not come across this before - is it possible
for you to give me some pointers on how to do this on win32?
thanks again

Hi,
I will assume that you want only the file open dialog for the save dialog
you need to do the same. You need to make the following changes in os.c file
from the sources of SWT dll.
- locate in os.c file GetOpenFileNameW or GetOpenFileNameA depending if
it's unicode platform or not
- befor the following line rc =
(jboolean)GetOpenFileNameW((LPOPENFILENAMEW)lparg0); you need to set in the
Flags member OFN_ENABLEHOOK and OFN_EXPLORER flags, also you need to set the
lpfnHook member to OFNHookProc() this will be your hook procedure.
- declare your hook procedure before this JNI function like this:
UINT_PTR CALLBACK OFNHookProc(HWND hdlg, UINT uiMsg, WPARAM wParam, LPARAM
lParam){
- in this hook procedure you need to process the WM_INITDIALOG message
and center the messagebox
- build the new DLL and use this one
I made those changes to make some tests, but there is a problem with this
hooking thing, form MSDN:
"For compatibility reasons, the Places Bar is hidden if Flags is set to
OFN_ENABLEHOOK and lStructSize is OPENFILENAME_SIZE_VERSION_400". I did'nt
find yet how to get rid of this.

Boby
