Hi,

i am using zest GridLayoutAlgo in my graph. By default when the layout is set, nodes get drawn in a gradual way like a fishman throw his net to the water...nodes emerge from the 0,0 coordinate to the preferred sizes and locations.. do you know what i mean?
Ok my question is I want to stop this so that when I update the graph it didn't disappear and then appear in this way.

Thank you!
Mok

Hi,

what you are interested in turning animations off. It was implemented for the http://wiki.eclipse.org/GEF/GEF4 version of Zest for bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=238529.

Cheers,
Zoltán

Hi,

but i am using GEF 3.8.XX and in the GEF website GEF4 is not published. In the link you gave, there is this updatesite
https://hudson.eclipse.org/hudson/job/gef4-master/lastSuccessfulBuild/artifact/update-site
should i deinstall my gef 3.8 and install the gef4? because i fear that gef4 is totally another api that will mess what i did.

Thanks,
Mok

Hi,

You can safely install GEF4 next to the GEF 3.8 API, as they are using completely different namespaces. On the other hand, this means, you have to migrate your existing Zest 1.x application to the new API - basically, bundles and packages are using the org.eclipse.gef4.zest namespace instead of the org.eclipse.zest, and you have to decrease the usepackage version numbers to 0.1.0 in the manifest.mf.

Cheers,
Zoltán

Hi,

in GEF4 Zest, animations are turned off by default, and you can turn it on by setting the 'animationEnabled' property on the Graph. See the http://git.eclipse.org/c/gef/org.eclipse.gef4.git/tree/org.eclipse.gef4.zest.examples/src/org/eclipse/gef4/zest/examples/layouts/TreeLayoutExample.java example mentioned in the previously linked ticket that turns on/off animations using a checkbox.

If you are speaking about 1.x Zest, I don't know, how to turn off animations easily.

Hi, I need your help again Confused

Can you tell me how can I pass my data object to the constructor of gef4 GraphNode??

In gef 3.8, I used to create my graphNode and pass an object to the constructor of the super too. This object is the data param which i will get inside initFigure() method. But the constructor in gef4 GraphNode that I need is deprecated or invisible. I used as suggested .setData(myDataObject) but the initFigure() is called before the field is set.
Thank you
Mok

Hi,

if I understand your issue, you want to add some data to a custom figure.

To solve this, I would either have a look at the implemented UML example http://git.eclipse.org/c/gef/org.eclipse.gef4.git/tree/org.eclipse.gef4.zest.examples/src/org/eclipse/gef4/zest/examples/uml/UMLExample.java

Or I'd rather use the JFace API with a LabelProvider also implementing the IFigureProvider interface. This way, it should be easier to pair data objects with Figures.

Cheers,
Zoltán
