// Minimal update test program for the Fast Light Tool Kit (FLTK).
|
|
//
|
|
// This is a test of the minimal update code. The right slider has a
|
|
// label that extends outside it's border, and the minimal update
|
|
// assummes this does not happen. Thus there is *supposed* to be
|
|
// display errors when you move the right-most or any other slider.
|
|
// If you *don't* see these errors, then the minimal update is
|
|
// broken!!!
|
|
//
|
|
// I cannot emphasize how important it is to test this and make sure
|
|
// any changes have not broken the minimal update. These sort of bugs
|
|
// are extremely hard to fix and must be detected right away!
|
|
//
|
|
// The reason it is important to fix this is that otherwise you will
|
|
// swiftly end up with a toolkit that thinks it has to draw the window
|
|
// 20 times each time the display changes. I don't care how fast the
|
|
// machine is, this is an insane waste of resources, and should be
|
|
// stopped!
