Widgets are components that are normally visual and the user can see +them and possibly interact with them at runtime.

+

TWidget has many protected properties and methods that are used or +published by its descendants. +

+

If you want to use a TWidget to hold child widgets you will probably +want to add a layout to the parent TWidget.

Sets or Gets the widget's GUI style. The ownership of the style object is not transferred. +

+

If no style is set, the widget uses the application's style, TApplication.DefaultStyle instead. +

+

Warning: +This function is particularly useful for demonstration purposes, where you want to show +fpGUI's styling capabilities. Real applications should avoid it and use one consistent GUI style instead. +

Set SmallChange to specify how much to change the value of Position +when the user clicks on the arrow buttons. The Max and Min properties define the +total range over which Position can vary.

+

For example, if Max is 100 and Min is 0, the scroll box can assume 100 +positions. If the SmallChange property setting is 5 and the Position property +is 0, the user can click the down or right arrow button 20 times before the +thumb tab is moved all the way to the end of the scroll bar.

+ + + + + + Determines how much Position +changes when the user clicks the scroll bar on either side of the thumb tab or +presses PgUp or PgDn. + +

Set LargeChange to specify how much to change the value of +Position when the user clicks on the side +of the thumb tab (that is, on the +thumb tab track, but not on the thumb tab itself). The Max and Min properties +define the total range over which Position can vary.

+

For example, if Max is 100 and Min is 0, the scroll box can assume 100 positions. + If the LargeChange property setting is 20 and the Position property is 0, the +user can click the scroll bar track five times after the thumb tab before it +moves all the way to the end of the scroll bar (100 / 20 = 5).
