| − | == Introduction ==
| + | Delete me. |
| − | This is an example which creates a light, non-comprehensive framework for PyCEGUI, with the rendering system used being [Py]OpenGL. The reason OpenGL is used is because it's free, easy to get on any Ubuntu system (which this was written on), and portable. Also, it's the one demonstrated on the official [[PyCEGUI]] page.

| − | == General notes ==
| + | |
| − | This is not intended to be fully comprehensive; rather, the intention is to illustrate '''one way''' of setting up a GUI system. A minimal amount of thought was given to "problems down the road;" which is to say that there is no guarantee that a particular design constraint will not render the framework unsuitable for a particular purpose.

| + | |
| − | To further demonstrate usage of how to manipulate the widgets and branch the script/code divide, consider the following modification to the `demomenu.DemoMenu.buttonClicked` method:
| + | |
| − | | + | |
| − | <source lang="python">
| + | |
| − | def buttonClicked(self, args):
| + | |
| − | editbox = self.menu.getChild('DemoMenu/Edit')
| + | |
| − | print(editbox.getText())
| + | |
| − | return
| + | |
| − | </source>
| + | |
| − | | + | |
| − | Now, when the button is clicked, it will print to the console whatever has been typed in the box.
| + | |
| − | | + | |
| − | As an exercise to the reader, consider adding support for Backspace/Delete/Arrow keys (hint: Special) keys.
