<h2>LayoutAnchors</h2>
|
||
|
|
A class that implements Delphi's Anchors with wxLayoutConstraints.
|
||
|
|
<p>
|
||
|
|
Anchored sides maintain the distance from the edge of the
|
||
|
|
control to the same edge of the parent.
|
||
|
|
When neither side is selected, the control keeps the same
|
||
|
|
relative position to both sides.
|
||
|
|
<p>
|
||
|
|
The current position and size of the control and it's parent
|
||
|
|
is used when setting up the constraints. To change the size or
|
||
|
|
position of an already anchored control, set the constraints to
|
||
|
|
None, reposition or resize and reapply the anchors.
|
||
|
|
<p>
|
||
|
|
Examples:
|
||
|
|
<p>
|
||
|
|
Let's anchor the right and bottom edge of a control and
|
||
|
|
resize it's parent.
|
||
|
|
<p>
|
||
|
|
<pre>
|
||
|
|
ctrl.SetConstraints(LayoutAnchors(ctrl, left=0, top=0, right=1, bottom=1))
|
||
|
|
|

|

|
|
* = anchored edge
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
When anchored on both sides the control will stretch horizontally.

ctrl.SetConstraints(LayoutAnchors(ctrl, 1, 0, 1, 1))
