[Help-smalltalk] VisualGST

[Gwenael Casaccio]

Hello everybody,

Some news about VisualGST, if you try the master branch of VisualGST you 
will two majors changes; a source code widget this is a classical
text editor with the full class sources. The method categories and
the methods are merged into one widget. The migration is not totally 
finished but it takes a good shape.

Internal changes:

State is used to update the browser which simplify a lot the code and
improve a bit the speed; I've updated the GtkTreeView/GtkListView widget 
to made it more simple and Smalltalk friendly:

  treeWidget := GtkScrollTreeWidget createListWithModel: 
{{GtkColumnPixbufType visible. GtkColumnTextType title: 'Methods'}}.
  (model := GtkListModel on: treeWidget treeView getModel)
                     contentsBlock: [ :each |
                                {each methodViewIcon.
                                 each selector asString} ].

For a tree:

    treeWidget := GtkScrollTreeWidget createTreeWithModel: 
{{GtkColumnTextType title: 'Classes'}}.
    treeWidget connectToWhenPopupMenu: (ClassMenus on: self).
    treeWidget treeView getSelection setMode: self selectionMode.
     (model := GtkTreeModel on: treeWidget treeView getModel)
                      item: self root;
                      childrenBlock: [ :each | self subclasses: each ];
                      contentsBlock: [ :each | {each asClass name 
asString, ' '} ].


Append is really simple too:

  myTree append: anObject.

or

  myTree append: anObject parent: aParentObject.


Feel free to reuse GtkMainWindow widget and those widgets for your Gtk 
project ;-)

Simple tasks for VisualGST:
===========================

  - testing with bug reports
  - improve again GtkScrollTreeWidget some ideas:
      treeWidget treeView getSelection
                setMode: GTK.Gtk gtkSelectionBrowse.
      replace by:
      treeWidget aNiceMessage :)

  - GtkListModel "integrated" into GtkScrollTreeWidget:
      treeWidget contentsBlock: [ :each |
                                {each methodViewIcon.
                                 each selector asString} ].
  - other idea for GtkTree* a message like expand: anObject
    and the isExpanded: anObject

Cheers,
