B4J Question Resize Pane

[Blueforcer]

Hi,i have a draggable pane in my gui, so the User can move it to another place.
Is it possible that the User can also resize it, like a normal window?

Something like this? See post#6

Looks good. there are some dependencies missing. like jMouseEvent and NodeWrapper, Can you tell me where i can get it?

Just realized and am looking them out now.

Try this one, I've put all of the required modules in the project. It's overkill for what you want but you can take what you want from it. See post #6

I've stripped the zoompane out of this one, probably easier to see what you need. Sorry, should have done that before posting in the first place

Works like a charm! Thank You

This works fine if a pane is placed inside the root or main, but if I create a pane then load a layout inside that newly created pane, then everything goes out of whack, meaning that the cursor doesn't change accordingly, for example if I put the mouse over the top left corner the Move cursor shows up when it should be the NE_RESIZE cursor, how to fix this?

Can you upload a small project that shows the problem?

Here is a small project, is basically your same example but I have added an extra pane, and added the two smaller panes inside of this parent pane.

The initial code was not written to account for the panes being added to a parent, and did all calculations based on the Root pane as the parent.

This version determines the absolute offset for the views by traversing up the tree until it finds an AnchorPane. This will obviously fail if you actually add an AnchorPane to the layout (which you shouldn't), but if you absolutely have to, the you will need to amend the code and pass the root pane to the initialize method and test for equivalence in the loop that calculates the absolute ParentX and Y.

Thank you very much, that seems to work great.
