TFlowPanel class

In unit ExtCtrls

Implements a panel with flowed layout for its controls.

Declaration

pascal

TFlowPanel = class(TCustomFlowPanel)

Inheritance

Description

TFlowPanel is a TCustomFlowPanel descendant which implements a panel used to automatically position controls added to the panel in a grid-like layout.

The FlowStyle property determines layout direction for controls added to the panel.

FlowLayout controls the vertical positioning for controls in given row on the panel.

The ControlList property provides a list of wrapper classes maintained for each of the controls on the panel. Its items maintain the position and wrapping options for each control using the FlowStyle and FlowLayout algorithms.

Adding a control to the panel causes it to be positioned at the next cell in the layout. The Left and Top coordinates for each control are adjusted to position the control within a cell using the FlowStyle and FlowLayout properties for the panel. The Anchors and Align properties for child controls are ignored. The BorderSpacing setting for the controls is used, however.

AutoWrap indicates whether the controls are automatically flowed into rows based on their settings in ControlList.
