Splasher A very simple application that displays a "modal" window that goes away as soon as you click the mouse or press a key. This is how many splash screens behave -- but as long as the window is displayed, the Process Manager won't switch your application from being frontmost. Toolbox
Sys7 popUpCDEF A simple example of using the PopupCDEF available in System 7 and later. Toolbox
TestGestalt These sample applications show how to use Gestalt to get information on system features. Toolbox
TwoColumn LDEF This LDEF looks for a comma in the text of each cell and draws the text that follows the comma half-way across the cell. Toolbox
'vox ' recording This application uses Quad buffering for both recording and playback. The recording is done with vox recording on, so it only records sound which is at least of a certain level. Toolbox
WaveTable Sounds These snippets show how to use waveTableSynth and squareWaveSynth. Toolbox
WDEFColorSample This sample shows how to obtain the colors that embellish System 7 window, and was written for developers who found the system 7 WDEF too obscure. Though I tried to make it resemble the WDEF organization, it is NOT a sample on how to write one. Toolbox
WDEFPatch This snippet shows how you can add a simple extra part to an existing WDEF and be able to do hit testing on the part via FindWindow(). The extra part in this case is on the right side of the title bar, just to the left of where the zoombox would be. When hit, it inverts the window. Toolbox
WindowColors This application displays the default window colors stored in the System's 'wctb' resource. Note that this app is 7.0 only, since it only recognizes the 7.0 version of the resource. Toolbox
ZoomWindow Demonstrates how to properly zoom a window. It gives attractive results with most WDEFs because it uses the window’s structure region rather than just its portRect. Toolbox
