wxRichMessageDialog: "GtkDialog mapped without a transient parent. This is discouraged."

[nourgaliev]

I am using wxRichMessageDialog to manage my messages. Works like a charm on Mac. On Linux, using gtk2/3, I am getting very annoying messages, something like:

wxWidgets/wxWidgets/src/gtk/toplevel.cpp(1257): assert ""m_widget"" failed in DoSetSize(): invalid frame
Gtk-Message: 13:21:27.524: GtkDialog mapped without a transient parent. This is discouraged.

And it pops window. I could shut down this for a particular run, but this is not acceptable long term solution.

Any suggestion to handle this? This is apparently warning, it not necessary crashes the code, but not really nice... My suspicion that parent window somehow was not passed to gtk, and will freak out.

Thanks in advance!

Robert.

What did you pass as parent for the dialog?

[nourgaliev]

Current window (this), I am calling from. It is wxFrame.

Please show the code for the event handler, and how you Bind it to the event.

Event is binded as:

this->Bind(wxEVT_BUTTON, &edit_nodes::on_help, this, wxID_HELP);

[nourgaliev]

It works fine on Mac. On gtk - pops windows with error, but when I choose continue - it goes further fine. If I choose do not show this message again - no windows pop up anymore for the rest of the code running.

Any problem with my derived class?

[nourgaliev]

I think the problem is with my derived class. When I do directly - everything is fixed. My bad. Thanks!

[nourgaliev]

I wanted to customize this class - but, apparently, you should not do that. Somehow - it screwed parent window...

In principle this should work. And i can't spot any obvious bug in your code.

I know - this is why I did not even tried without derived. It was not on my "to check list". In any case - I abandoned idea of customizing, in any case - as something I wanted to change - did not work anyway.

Thanks.

Hi,
What you did want to change?

Thank you.
