Dialog and minimize, maximize buttons

[lotek]

In the Qt::dialog Window Flag description one can read: "decorated as a dialog (i.e., typically no maximize or minimize buttons in the title bar)"

Any idea why this does not work (at least under Linux)?

I can get either the whole Title Bar (with minimize/maximize buttons) or nothing.

How to eliminate the minimize/maximize buttons in Dialog?
(Arithmetical & with negation of according flags does not work)

thanks for your help

Try this:
setWindowFlags(Qt:ialog);

That gives me a dialog with a title bar and a close X but no minimize or maximize buttons.

Ignore the icon, it's Qt: Dialog without the space.

Thanks for the answer, but exactly this (and some other things) does not work on Linux. I suppose you are working on Windows. I am afraid, that it is the the X Manager feature and I can't remove this stupid buttons. Even the dialog examples have the minimize/maximize buttons, and there is nothing to do to get rid of them.

Yes, I am working on Windows, for now. But from what you said, I will have the same problems when I go over to Linux.

Hi,

The maximize button disappears when the setMaximumSize() method is called for a dialog.

For the context help button the arithmetical & with negation of the Qt::WindowContextHelpButtonHint flag works.

Qt::WindowFlags f = windowFlags();
f &= ~Qt::WindowContextHelpButtonHint;
setWindowFlags(f);

Only the minimize button stays, but i can live with it.

You should set "Qt::CustomizeWindowHint" for window flags,

setWindowFlags(Qt::Dialog | Qt::CustomizeWindowHint | Qt::WindowTitleHint);

setWindowFlags(Qt::Dialog | Qt::CustomizeWindowHint | Qt::WindowTitleHint);

To copy to clipboard, switch view to plain text mode

Nice idea, but sorry...

I've already checked it. on Linux ( SuSE 11.2) the minimize and maximize buttons ale still visible. The close button and context help button disappear.

Anyway thanks for the hint!

hi,
In Debian its working. It should work with windowflags ,
try Qt::FramelessWindowHint and if u want to show a title ,add a QLabel and show ur title.

Or Try window styles, like motif,kde etc using QStyle

Thnks

I used this and it works with Ubuntu 9.10 and 10.04,
Please when you found the solution, write it here.

Works well in Ubuntu 10.04

All buttons visible and all buttons enabled: setWindowFlags(Qt::Tool)
All buttons visible, close and maximize buttons enabled, minimize button disabled: setWindowFlags(Qt::Tool | Qt::WindowTitleHint | Qt::WindowMaximizeButtonHint | Qt::WindowCloseButtonHint | Qt::CustomizeWindowHint)
All buttons visible, maximize button enabled, close and minimize disabled: setWindowFlags(Qt::Tool | Qt::WindowTitleHint | Qt::WindowMaximizeButtonHint | Qt::CustomizeWindowHint)
Only close button is visible and enabled setWindowFlags(Qt::Tool | Qt::WindowTitleHint | Qt::WindowCloseButtonHint | Qt::CustomizeWindowHint)
No buttons in title bar: setWindowFlags(Qt::Tool | Qt::WindowTitleHint | Qt::WindowCloseButtonHint | Qt::CustomizeWindowHint)

If i am understanding this problem correctly then this works with Qt4 on Ubuntu 10.10

w.setWindowFlags(Qt::Tool);

add that line before w.show() in your main.cpp and all you will have is the close button
