Win32: Choosing background-color for widget



Hi,

well i want to make a pick-a-color-button with a button and a ColorSelectionDialog Widget. The picked color should be the new backgroud color of the button. Well the code itself works, but I still get an error. These are parts of my code:

GtkColorSelection *temp_color;

// The callback for the color-button
void color_button_clicked (GtkButton *button, gpointer user_data) {
  GtkWidget *col_sel;
 
  col_sel = gtk_color_selection_dialog_new  ("Choose color");
 
  g_signal_connect_swapped (GTK_OBJECT (GTK_COLOR_SELECTION_DIALOG (col_sel)->cancel_button),
                            "clicked",
                            G_CALLBACK (gtk_widget_destroy),
                            (gpointer) col_sel);
  g_signal_connect (GTK_OBJECT (GTK_COLOR_SELECTION_DIALOG (col_sel)->ok_button),
                    "clicked",
                    G_CALLBACK (apply_color), button);
  g_signal_connect (GTK_OBJECT (GTK_COLOR_SELECTION_DIALOG (col_sel)->colorsel),
                    "color_changed",
                    G_CALLBACK (update_temp_color), NULL);
                       
  gtk_widget_show (col_sel);
}

// apply color to button
void apply_color (GtkWidget *button, gpointer user_data) {
  GdkColor *temp;

  gtk_color_selection_get_current_color (temp_color, temp);
  gtk_widget_modify_bg (GTK_WIDGET(user_data), GTK_STATE_NORMAL, temp);
}

// temp-color is global. It is used to store the actual color
void update_temp_color (GtkColorSelection *colorselection, gpointer user_data) {
  temp_color = colorselection;
}


Well, sometimes it works quite fine, but mostly I get an error in libglib-2.0.0.dll. Im using DevC++ 4.9.8.0.

Does anyone know whats wrong? I'm really stuck with my program, due to that, so I would really appreciate your help. Thanks!

Greets,
