Asuming the folowing widget layout:
type myLeaf struct {
node.LeafEmbed
// some other fields
}
func NewMyLeaf() *myLeaf {
w := &myLeaf{}
w.Wrapper = w
return w
}
func (w *myLeaf) Paint(ctx *node.PaintContext, origin image.Point) error {
w.Marks.UnmarkNeedsPaint()
// draw to ctx ...
}
Inside driver.Main()
:
leafA := NewMyLeaf()
leafB := NewMyLeaf()
w := widget.NewFlow(widget.AxisVertical,
widget.NewSheet(leafA),
widget.NewSheet(leafB),
)
if err := widget.RunWindow(s, w, &widget.RunWindowOptions{
NewWindowOptions: screen.NewWindowOptions{},
}); err != nil {
log.Fatal(err)
}
How does one execute func (w *myLeaf) Paint(...) error
on the widget tree for each leaf (myLeaf
) from outside driver.Main()
?
Also using pointers for leafA
, leafB
and w
is possible.
