I have built an application based on the GTInspector. Hurray!

Looks really nice!

Now I want to share it and I need to write documentation. I would like to include screenshots in the docs but I don't want to create them by hand.

So my question is: Is there an easy way to automatically generate screenshots for GTInspector extension methods? e.g. to specify an object and the name of a presentation and to get a PNG file of how that looks in the GTInspector.

To add to Juraj's email you can use something like the following:

inspectorWindow := GTInspector inspector: Morph new.

inspector := inspectorWindow model.

inspectorsPresentations := inspector panes first presentations first cachedPresentation first.

inspectorsPresentations pane lastActivePresentation: (inspectorsPresentations presentations detect: [ :each|

each title = 'Morph']).

morph := inspectorWindow.

"morph exportAsPNG."

file := Smalltalk imageDirectory / morph externalName, '.png'.

PNGReadWriter putForm: morph imageForm onFileNamed: file.

inspectorWindow close.

This opens an inspector, selects a certain presentation based on its title and then exports the entire inspector window as a png.

If you want to export only certain parts of the inspector you can play with Morph>>#allMorphsDo: to locate within the inspector window for example only the morph showing a certain presentation.

Thanks!

P.S. References to how other people write their docs in general would be interesting.

I usually use pillar :). There are several extension for the inspector that you can use to edit pilar documents.

P.P.S. Here is GTInspector browsing internal data structures of a JIT compiler :-)

Quite nice!

Cheers,

Andrei
