Introduction The GtkCalendar widget is used to display a calendar to the screen, one month at a time. For the purpose of this example, we are not setting the date on the calendar. In a real world program, you will want to get the system date and set the date  [ Read More ]

Introduction The GtkFileSelection widget allows for GTK+ programs that utilize it to have a consistent file dialog window. The standard GtkFileSelection widget can be extended and customized, but for the purpose of this example, we are using the standard file dialog box.

Introduction This example produces a GTK Color Selection Area. It allows the user to choose any color value from a color wheel or by typing in the RGB values. Source Code /* *File name: colorselection.c */ #include #include /*– This function allows the program to exit properly when the window  [ Read More ]
