Window controls
Specifies an optional animation effect that displays when the window closes.
The CloseAnimation property takes a value of the WindowAnimationStyle enumerated variable. For “slide” values, the whole window appears to slide from the direction selected. For “roll” values, the window does not move but its display is cleared from the direction selected. Values are:
NoAnimation! (default) – The window closes with no animation.
TopSlide! – The window slides from the top to the bottom of its extent.
BottomSlide! – The window slides from the bottom to the top of its extent.
LeftSlide! – The window slides from the left to the right of its extent.
RightSlide! – The window slides from the right to the left of its extent.
TopRoll! – The window rolls from the top to the bottom of its extent.
BottomRoll! – The window rolls from the bottom to the top of its extent.
LeftRoll! – The window rolls from the left to the right of its extent.
RightRoll! – The window rolls from the right to the left of its extent.
FadeAnimation! – The window fades out.
CenterAnimation! – The window collapses from the center.
You can modify the animation properties at any time and use them for any window type. They are most often used in pop-up windows.
FadeAnimation! can be used only in top-level windows. It does not work in child windows. In MDI applications, you cannot use FadeAnimation! for sheet windows. Fading affects the transparency of the window, and sheet windows in MDI applications always inherit the transparency of the frame window.
Also, if the Transparency property of a frame or main window is set to a value above 0, the TopRoll!, BottomRoll!, LeftRoll!, RightRoll!, and CenterAnimation! settings do not work with sheet windows or child windows. All settings work correctly for frame windows.
While the animation executes, the application waits for it to complete. Use the AnimationTime property to control the number of milliseconds the animation takes to execute.
The window’s CloseQuery event is triggered before the animation begins. The Close event is triggered when the animation has completed.
To set the CloseAnimation property on a window:
Select a value from the CloseAnimation drop-down list on the General page of the window’s Properties view.
The following example sets the CloseAnimation property of the w_splash window to FadeAnimation!:
w_splash.CloseAnimation = FadeAnimation!
