adding atoms to layout

Rate this Message:
Hi
I am adding a few atoms to layout. After all atoms were added I would like to start "next task". The atoms are added in random order therefore I don't know which one is last. It cannot be solved by add appear event to each atom due to "next task" should be start only one time and all atoms should be visible. My question is how to trigger "next task" when all atoms appear on layout ? Thanks, Karol |

It might help if you explain a little what "next task" is, and also why
these atoms are added in random order. If you know how many atoms are added, and you want to wait until they are all onscreen you could use the appear event and a counter. var count = 0; eachAtom.addListener("appear", function() { if (++count == numberOfAtoms) { this.nextTask(); } }, this); As I said, if you give more detail we might be able to help more :) Matt Grykar wrote: > Hi > > I am adding a few atoms to layout.

Matt,
thanks for this hint. I test it today. I have to wait for all atoms because "next task" reads position of them. Karol

unfortunately it doesn't work for me because I need acccess to all atoms
please see how it works. Login as demo no password is needed http://family3.org/tree_/build/index.html the next task is to draw relation between atoms Karol

When all atoms apper I would like to draw relations between them. To do that I have to read positions of all atoms then draw. I have no access to atom position before atom appear. It is due to complexity of application.
The first workaround I aapplied was alert message before drwing relations. It gives additional time to finsh adding atoms to layout but it was not user friendly. The current workaround is time event added behaind the loop of adding atoms: qx.event.Timer.once(function(e){ this.drawRelations(); }, this, 1); Generally it works but sometimes it is unstable Probably I have to redesign application to have access to atoms position before thay appear on layout. Thanks, Karol
