Dimension of Custom Components [message #58323]

Hi,

I just realized, that a Custom Component i wrote does not integrate right
into our Application.
The Component Overlapps the Components which are near to it, so I suspect,
that the widht and height are not correctly reported.
Where can I adjust this? IŽm not so experienced in JS and I cant find a
way to fix this.

Thank you

Martin

It is even worse, it seems
as if the component isnŽt recognized by the layout at all.
What can that be?

Thank you

Martin

Hi,

I managed to get it working by overwriting computeSize() in my widget.
The 100 $ Question is now, does I always have to provide an own
implementation
of computeSize?

Kind regards

Hi,

not always but very often :-)

If your control is made of texts for example you have to determine the sizes
of those texts add margin, padding, border etc. to get the preferred size of
your control (This is the size in which position and size of those texts are
optimal for a proper layout). This is nothing that can be done automatically
by the system. But if your control extends Composite for example and your
control makes use of the composite pattern using a certain layout for
control positioning into the control the original computeSize method of the
Composite should be sufficient.
