The images on toolbar are automatically scaled down from 48x48 to 16x16, so I get something like this

the toolbar has 2 buttons (48x48), but both images appear on the first button.

This is the toolbar source code:

CXTPCommandBars* pCommandBars = GetCommandBars();

pCommandBars->SetMenu(_T("Menu Bar"), IDR_MAIN_MENU);

CXTPToolBar* pToolBar = pCommandBars->Add(_T("Main"), xtpBarBottom);

if (!pToolBar || !pToolBar->LoadToolBar(IDR_TOOLBAR, FALSE))

{

TRACE0("Failed to create toolbar\n");

return -1;

}

XTPImageManager()->SetIcons(IDR_TOOLBAR, IDB_MAINTOOLBAR);

pCommandBars->SetTheme(xtpThemeOffice2007);

pCommandBars->GetCommandBarsOptions()->szLargeIcons = CSize(48, 48);

pCommandBars->GetCommandBarsOptions()->bLargeIcons = TRUE;

Why the images are not displayed at their original size of 48x48 pixels ?

Thanks !

IDR_TOOLBAR TOOLBAR 48, 48
BEGIN
BUTTON ID_MAIN_EXIT
BUTTON ID_MAIN_TEST
END

...I have also tried with IDR_TOOLBAR TOOLBAR MOVEABLE PURE 48,48 just like in WinZip GUI sample..., but I got the same result.

....and this is the menu

IDR_MAIN_MENU MENU
BEGIN
    POPUP "Main"
    BEGIN
        MENUITEM "E&xit",                       ID_MAIN_EXIT
        MENUITEM "Test",                        ID_MAIN_TEST
    END
END

Hi,

The PNG bitmap is 288x48 pixels and in debugger SetIcons function loads 2 icons with the size of 48x48

I have tried a PNG with the size of 96x48 and now the bitmaps are displayed correctly !

It seems that SetIcons loads the entire bitmap, no matter what size you specify in szLargeIcons and then it just slices the bitmap according to the number of toolbar buttons and then it scales the image to fit in toolbar, very strange behaviour.

You should specify in documentation or in sample source code as a comment that // The Toolbar bitmap should be the exact size or it won't display correctly.

Thanks Oleg !

You have a great supprt !
