Hi
Platform: Win32/VC++
In my app I have a rebar with one toolbar child. My problem is when the toolbar height changes (because I add option to customize toolbar and to hide/show toolbar buttons text) the rebar band height is not changes as auto! Is there a way to do it auto or I have to update band info data after each time toolbar customized?
Thanks
If I call RB_SETBANDINFO with RBBIM_CHILDSIZE and cxMinChild & cyMinChild, it works if I test on the MS sample after having changed the Toolbar height :
Hello,
Welcome to Microsoft Q&A!
The REBARBANDINFO structure members define the traits of a given band. To set a band's traits, set the cbsize member to indicate the size of the structure, in bytes. Have you set the cbsize member? Try to create the Rebar first and then create toolbar control.
If I misunderstand you, could you please provide the sample to help us reproduce the issue?
Thank you.

Parts of my code: I tested to create first rebar but not helps
HWND hWndToolBar = toolbar.Create(hWndParent, NULL, NULL, WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | CCS_NODIVIDER | CCS_TOP | TBSTYLE_FLAT | TBSTYLE_TOOLTIPS, 0, IDW_TOOLBAR);
/**/
then create rebar:
HWND hWndReBar = CreateWindowEx(WS_EX_TOOLWINDOW, REBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | WS_CLIPCHILDREN | CCS_TOP | RBS_BANDBORDERS | RBS_VARHEIGHT, 0, 0, 0, 0, hWndParent, (HMENU)IDW_REBAR, Module::GetModuleInstance(), NULL);
if (hWndReBar == NULL)
return NULL;
RECT rectToolBar;
SendMessage(hWndToolBar, TB_GETITEMRECT, (WPARAM)0, (LPARAM)&rectToolBar);
REBARBANDINFO rbbi;
rbbi.cbSize = sizeof(REBARBANDINFO);
rbbi.fMask = RBBIM_CHILD | RBBIM_STYLE | RBBIM_CHILDSIZE | RBBIM_IDEALSIZE | RBBIM_SIZE;
rbbi.fStyle = RBBS_NOGRIPPER | RBBS_FIXEDBMP | RBBS_CHILDEDGE;
rbbi.hwndChild = hWndToolBar;
rbbi.cxMinChild = rectToolBar.right - rectToolBar.left;
rbbi.cyMinChild = rectToolBar.bottom - rectToolBar.top + 1;
rbbi.cx = rbbi.cxMinChild;
rbbi.cxIdeal = rbbi.cxMinChild * NUM_OF_MAIN_TOOLBAR_BUTTONS;
SendMessage(hWndReBar, RB_INSERTBAND, (WPARAM)0, (LPARAM)&rbbi);
/**/
main frame WM_SIZE handler:
SendMessage(hwndRebar, WM_SIZE, 0, 0);
Also area between top menu bar and the rebar is not painted!
Have you tried castorix 's suggestion? Try to call RB_SETBANDINFO message
Yes, I doing that before, but I expect Rebar do it auto but not updates bands height.
