BCB6
non-oriental windows
My question is quite simple: how to make the menu right aligned and
displayed from right to left when BiDiMode is set to RightToLeft, even in
non-oriental version of windows?
I know that in MFC the following code works (assuming mnuHandle and bdMode
are global vars for the example purpose):
void SetMenuDirection(void)
{
MENUITEMINFO mii;
char szBuffer [80];
//get current menu alignment
mii.cbSize = sizeof (MENUITEMINFO);
mii.fMask = MIIM_TYPE;
mii.dwTypeData= szBuffer;
mii.cch = sizeof (szBuffer);
GetMenuItemInfo(mnuHandle, 0, true, &mii);
mii.fMask = MIIM_TYPE;
if (bdMode == bdLeftToRight)
mii.fType = mii.fType & ~MFT_RIGHTJUSTIFY & ~MFT_RIGHTORDER;
else /* various bdRightToLeft */
mii.fType = mii.fType | MFT_RIGHTJUSTIFY | MFT_RIGHTORDER;
//update menu alignment
SetMenuItemInfo(mnuHandle, 0, true, &mii);
}
The "only" question is: where to put this code in BCB6?
The solution I think as the best is to write a TMyMainMenu VCL component
derived from TMainMenu, and to call SetDirection somewhere in the code.
I 've unsuccessfully tried to overload the following:
adjustBiDiBehavior
DoBiDiModeChanged
MenuChanged
IsRightToLeft
does anyone can help?

Well I am answering to myself: maybe it can help someone.
Well the solution is to derive a component from TMainMenu, then make the
SetMenuDirection a private method and overload the DoChange to make a call
to SetMenuDirection.
I have mixed this with a TAlignment property so it is changeable at runtime.
SetMenuDirection must be:
void SetMenuDirection(void)
{
MENUITEMINFO mii;
char szBuffer [80];
//get current menu alignment
mii.cbSize = sizeof (MENUITEMINFO);
mii.fMask = MIIM_TYPE;
mii.dwTypeData= szBuffer;
mii.cch = sizeof (szBuffer);
GetMenuItemInfo(mnuHandle, 0, true, &mii);
//update menu alignment
mii.fMask = MIIM_TYPE;
if (bdMode == bdLeftToRight)
mii.fType = mii.fType & ~MFT_RIGHTJUSTIFY & ~MFT_RIGHTORDER;
else /* various bdRightToLeft */
mii.fType = mii.fType | MFT_RIGHTJUSTIFY | MFT_RIGHTORDER;
SetMenuItemInfo(mnuHandle, 0, true, &mii);
//redraw the menu bar
TForm* parent = dynamic_cast<TForm*>(Owner);
if (parent) DrawMenuBar(parent->Handle);
}

chris
