wxWidgets Discussion Forum

Sorry, i'm out of ideas. I don't know anything about GTK, so i don't know what exactly this assert message indicates. Try opening a bug report at http://trac.wxwidgets.org

The sample is fine, thx. But unfortunately it doesn't crash for me, neither under Windows, nor under Ubuntu. But i tested with the latest wxWidgets from Github.

Do you still get the same assert with the same call stack?
What happens if you just remove the mp_button->Update(); call?

If the call to ShowModal() returns, the dialog will be closed. If you want to perform some action when the user clicks apply, but don't want the dialog to close, you need to do it inside the dialog code.

You need to call this when the user clicks on the "Apply" button and you want to close the dialog.

What can cause a infinite loop of EVT_DATAVIEW_SELECTION_CHANGED?

Doing something that causes another EVT_DATAVIEW_SELECTION_CHANGED event.

The problem lies in the dialog code, not the part you're showing.

For values other than wxID_OK and wxID_CANCEL, you need to set the return value of ShowModal() explicitly with wxDialog::EndModal().

hi i dont want to creare new thread. i want to ask in wxwidets its some function like show messages ? i want to create something like messenger and i want wxTextCtrl send to some global chat.. where should i start ? That's a very broad question. You can start by studying the "sockets" sample that c...

By the time OnSampleListViewContextMenuSelect is executed, the popup menu is already closed to about to be closed. It doesn't make sense to make any changes to the menu there. In OnShowSampleListViewContextMenu you must check if the item is already favorited or not, and dynamically decide which menu...

https://docs.wxwidgets.org/trunk/classwx_gesture_event.html I only know that the MSW implementation doesn't work at all, i don't know about the state under the other platforms. https://groups.google.com/g/wx-dev/c/JdeuH95_bGQ/m/tcJCXMZUDgAJ Check the "event" sample that comes with wxWidgets, it has ...

thanks now its working and what thoes mean ? this ID ? its just ID for button ? An "id" is used to uniquely "id"entify an object, in this case a wxButton. EVT_BUTTON(ID_BUTTON_REGISTER, AmiFrame::register_button) wxButton *register_button = new wxButton(this, ID_BUTTON_REGISTER, "Register", wxPoint...

i try to with wxid any and its same login opening register everytime but i domt know why No, you should *not* use wxID_ANY. wxID_ANY in an event table, it means "matches for any ID". And when passing it to constructor, it means "create a new ID". Where ever idMenuQuit and idMenuAbout are defined, j...

EVT_BUTTON(wxID_ANY, AmiFrame::register_button) wxButton *register_button = new wxButton(this, wxID_ANY, "Register", wxPoint(400, 300), wxSize(70,50), 0); You need to use a unique ID instead of wxID_ANY. I would also suggest to use a different ID for the login button, wxID_OPEN does not really fit ...

It seems that in your screenshot, the "Show info" button has Windows95 look (i.e., a 3D one) but the font picker has the proper themed (i.e., flat) look? Are my eyes deceiving me? I'm not sure, but i think this deserves more attention, especially since the original post mentions a "CommDlgExtendedE...

MS ID system will let ypou create only MAX_INT number of them.

The IDs are not the main problem, the 10000 GDI handle limit is

Your definition of "minimal" is slightly different than mine ;) "minimal" means it should not contain anything that's not needed to reproduce the issue, e.g. the whole wxTimer stuff. And we also don't know yet if setting any (good) bitmap can trigger the assert, or if it only happens when setting a ...
