measureElement method
Given the available size, measure one element of the Panel and determine its expected drawing size. This sets the GraphObject#measuredBounds of the object, which can then be used to determine the arrangement of objects in the PanelLayout.
Implementation
void measureElement(
_i3.GraphObject obj,
_i2.num width,
_i2.num height,
_i2.num minw,
_i2.num minh,
) {
_i4.callMethod(
this,
'measureElement',
[
obj,
width,
height,
minw,
minh,
],
);
}
