Hi,
I am trying to add test-cases in ContextMenuTest.java to test ContextMenu
positioning,
but the test cases fails since it ignores the css padding applied on the
ContextMenu's menu/menu-item via css.
Test-cases:
@Test public void test_position_showOnTop() { // fails
ContextMenu cm = createContextMenu(false);
cm.show(anchorBtn, Side.TOP, 0, 0);
final Bounds anchorBounds =
anchorBtn.localToScreen(anchorBtn.getLayoutBounds());
assertEquals(cm.getAnchorX(), anchorBounds.getMinX(), 0.0);
assertEquals(cm.getAnchorY() + cm.getHeight(), anchorBounds.getMinY(), 0.0);
}
@Test public void test_position_showOnRight() { // passes
ContextMenu cm = createContextMenu(false);
cm.show(anchorBtn, Side.RIGHT, 0, 0);
final Bounds anchorBounds =
anchorBtn.localToScreen(anchorBtn.getLayoutBounds());
assertEquals(cm.getAnchorX(), anchorBounds.getMaxX(), 0.0);
assertEquals(cm.getAnchorY(), anchorBounds.getMinY(), 0.0);
}
I can do the following to make the tests pass, but it doesn't feel write:
@Test public void test_position_showOnTop() {
...
cm.setOnShown(e -> {
final Bounds anchorBounds =
anchorBtn.localToScreen(anchorBtn.getLayoutBounds());
assertEquals(cm.getAnchorX(), anchorBounds.getMinX(), 0.0);
assertEquals(cm.getAnchorY() + cm.getHeight(), anchorBounds.getMinY(),
0.0);
});
}
What would be the correct way to fetch "css applied" height/width of
ContextMenu?

Hi Kevin,
Yes, this is actually a pre-review mail to know if I am on the right path.
Exposing these properties from ContextMenu can confuse users because the
control has overloaded show() method.
The second show() method doesn't use any of these properties and instead use
screenX and screenY to place the ContextMenu.
Given the circumstances, using Helper class seems the best solution to me. If
someone has a better alternate solution, I am all ears.

I presume this is a "pre" review before sending out an actual review
(which the Skara tooling will do automatically when you generate a pull
request)...
My concern with this approach is that it leaks what should be an
implementation detail into a visible property of the control (and
really, using the properties map in this manner is a bit of a
workaround). An alternative would be to use package scope methods and a
Helper class, which is done in many other places. Worth noting is that
if this is information that a custom skin would also need, then some
sort of way to make this visible to the Skin will eventually be needed.
