okay THANKX.
Now I can dynamically create Rect or simiular Object onto a Canvas.
I have to Buttons one for Create and the other for delete. I did all Object in a List or Array. The List is full with objects which inherit from compositeNode.
At Least I bind the hole list with select or foreach to the content.

jj: Elements like buttons do not have a sense of "canvas" - it's only Nodes (like CompositeNode) that have it. A composite node can reach to its parent canvas using the getCanvas() method, and then it should be able to access the content attribute. I suppose that if you create a function in a composite node that does something with getCanvas().content, and then assign the function to Button's action attribute (for example), it might work - but I haven't tried it. See if it works and let me know!

Sorry. I try it again.
The only thing I want is to generate dynamically Objects. It doesn’t matter if this is a Rect or something like that.
And the question was: I have a Canvas with some Object – and I want to add new Object (Views, Textfield, Rect) to the same Canvas. Also it have to be possible to get all objects from the Canvas – so can delete them.
Hope this was better ….

jj: I don’t understand your question… Are you looking to bind a rect to a button, or to have the rect as the button’s content?

Hi,
cool I like JavaFx.
One question for you is it also possible to add a Rect dynamical with a Button or something?
pseudocode:
button{
canvas.getContent().add(myRect)
}
Is this possible?

I don’t know why is wrong, but try to test it! It just dosen’t work…
I have test it in NetBeans 5.5 and here it is the error:

file:/C:/JavaApplications/JavaFXSamples/build/classes/FXSample.fx:7: Encountered “{” at line 7, column 8.

Why is it wrong to have the additional brackets?

Wrong:

import java.lang.*;
import javafx.ui.*;
import javafx.ui.canvas.*;

Canvas {
content: bind foreach (i in [1..10], j in [1..10])
{ Text { content: “{i*j}” x:i * 30 y:j * 30} }
}

Good…:

import java.lang.*;
import javafx.ui.*;
import javafx.ui.canvas.*;

Canvas {
content: bind foreach (i in [1..10], j in [1..10])
Text { content: “{i*j}” x:i * 30 y:j * 30}
}

Are you sure that this work (look at line 7):

import java.lang.*;
import javafx.ui.*;
import javafx.ui.canvas.*;

Canvas {
content: bind foreach (i in [1..10], j in [1..10]) {
Text { content: “{i*j}” x:i * 30 y:j * 30}
}
}
