GTK implementation of MessageBox


By : Nate3000

With these it helps I have been trying to implement Win32's MessageBox using GTK. The app using SDL/OpenGL, so this isn't a GTK app. , Hmm, ok. I'd suggest code like this, then:
code :
typedef struct {
    int type;
    int result;
} DialogData;

static gboolean
display_dialog(gpointer user_data)
{
    DialogData *dialog_data = user_data;
    GtkWidget *dialog;

    if (dialog_data->type & MB_YESNO)
        dialog = gtk_message_dialog_new(...);
    else
        dialog = gtk_message_dialog_new(...);

    // Set title, etc.

    dialog_data->result = gtk_dialog_run(...);

    gtk_main_quit();  // Quits the main loop run in MessageBox()

    return FALSE;
}

int MessageBox(...)
{
    DialogData dialog_data;

    dialog_data.type = type;

    gtk_idle_add(display_dialog, &dialog_data);

    gtk_main();

    // Do stuff based on dialog_data.result
}

With these it helps I'm trying to build a hello world using GTK, which includes the line: , You need to use pkg-config to get the include paths:
code :
$ pkg-config --cflags gtk+-2.0
-I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12
$ pkg-config --libs gtk+-2.0
-lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lpangoft2-1.0 -lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lgio-2.0 -lcairo -lpango-1.0 -lfreetype -lz -lfontconfig -lgobject-2.0 -lgmodule-2.0 -lglib-2.0

Correct implementation of WPF custom MessageBox using MVVM pattern


By : threedog2

wish of those help Your example is a correct use of MVVM pattern as you have a separate ViewModel to which I assume you bind to and which does not know about the View.
Possibly you can simplify the ViewModel by replacing ShowMessage function (which actually does not show a message I guess) with an Exception property and set it.
code :
void Current_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
{
    CustomMessageBoxViewModel messageBox = new CustomMessageBoxViewModel();
    messageBox.Sender = sender;
    messageBox.Exception = e.Exception;
    CustomMessageBoxWindow messageBoxWindow = new CustomMessageBoxWindow();
    messageBoxWindow.DataContext = messageBox;
    messageBoxWindow.ShowDialog();

    e.Handled = true;
}

MessageBox In GTK Never Shown

it fixes the issue I think you want btnClick.Clicked rather than btnClick.ButtonPressEvent. There doesn't even seem to be a ButtonPressEvent member. See http://docs.go-mono.com/?link=T%3aGtk.Button

Can't find implementation of gtk_menu_shell_get_type (gtk)


By : Bro Nas
Date : March 29 2020, 07:55 AM
I wish this helpful for you gtk_menu_shell_get_type function is defined in gtkmenushell.c. It's not declared directly. Instead, macro G_DEFINE_ABSTRACT_TYPE_WITH_PRIVATE is used to declare it.
See example for G_DEFINE_TYPE_EXTENDED.
