Custom Tooltip with WS_POPUP Dialog Box

I want to create custom tooltips where I can place any controls. I got from CDialog and used styles WS_POPUP | WS_BORDER

. I also add styling CS_DROPSHADOW

to OnInitDialog to get the shadow of the tooltip.

Then I manage events WM_MOUSEHOVER

and WM_MOUSELEAVE

to show / hide the tooltips.

I am showing the tooltip with SetWindowPos

and SWP_NOACTIVATE

to prevent the parent from being included and the new dialog becomes active. But anyway, when I create a dialog using the method CDialog::Create

... the main window becomes inactive ... which makes a very bad effect.

So my question is, how do I create a CDialog with type WS_POPUP without my main window (or parent dialog box), becoming inactive when a new dialog pops up?

Thanks for the help!

Edited: I am not using the WS_VISIBLE style to create a dialog ... this is this resource:

    IDD_LABEL_TOOLTIP_DLG DIALOGEX 0, 0, 100, 9
    STYLE DS_SETFONT | WS_POPUP | WS_BORDER
    FONT 8, "Tahoma", 0, 0, 0x0
    BEGIN
       LTEXT           "##################",IDC_TOOLTIP_LBL_TEXT,0,0,99,9
   END

The code that displays the tooltip looks something like this:

if(!pTooltipDlg)
{
    pTooltipDlg = new MyCustomTooltipDlg();
    pTooltipDlg->Create( MyCustomTooltipDlg::IDD, this);
}
pTooltipDlg->ShowWindow(SW_SHOWNOACTIVATE);

The first time (i.e. when the call is created) the main windows lose focus ... the rest of them this ugly effect doesn't happen ... so I'm pretty sure it has to do with creation.

Ok. I finally got it! I just needed to return FALSE in the OnInitDialog method to avoid activating the dialog.



Thank you everybody!

When you create your window, do not set the WS_VISIBLE flag on it. Then you can use ShowWindow with SW_SHOWNA or SW_SHOWNOACTIVATE to make the dialog visible.

Are you calling CDialog::Create()

with WS_VISIBLE

? Perhaps even just summoning Create()

enough to keep the parent focused. It might be worth overriding WM_SETFOCUS

in your tooltip class and not calling the base class to make it impossible to change the window focus.

First of all, consider using CWnd and not CDialog. This gives you much finer control. And you don't use any of the CDialog functions at all other than the dialog template; it's not that hard to dynamically create your controls.

You can also look into the message handlers handling the OnShowWindow and make sure any show commands are changed to SW_SHOWNA, as in Mark Ransom's comment.

Also, the parent window should probably be NULL as a tooltip.
