I'm using Tulip 4.1 for my own network topology visualization application and I'm coding in c++.
In this application I'm trying to represent the devices involved with their external and internal ports. In my idea, I would like to display them as much as possible in the way they really appear. Basically, create a box with some ports inside and outside.
To do this, I tried to make a node which all-encompassing the internal nodes and attach the external ones to its surface. But it seems that it is not possible to modulate the transparency of the nodes… Or I didn't find any way to change it !
Therefore, I tried to create a GlBox to achieve the same goal but again, I couldn't be able to change the transparency…
Does anyone has an idea ?
I not sure to well understand your problem but
I suppose that the edges overlapping transparent nodes are not visible.
You can solved this using the "Layers" panel of the Node link diagram view.
Just activate the "Stencil" of the Main->graph->Edges layer in this panel.
Hope this helps.
First of all, thank you for your quick answer !
In fact, I meant directly in the code, is it possible to modulate the transparency of nodes ?
Because it seems that the "alpha" coefficient in the colors property "viewColor" doesn't change nodes transparency but rather their brightness, am I right ?
