* - Open a FileChooserDialog, set to only view .code-workspace files.
|

|
* - If the user pressed cancel, destroy the dialog. If the user opened a .code-workspace file:
|
||
|
* - Get the workspace file, load and parse its content, .code-workspace files are in JSON with comments. But JSON only should be fine, for now.
|
||
|
* - Iterate over folders listed in the workspace file.
|
||
|
* - Find the absolute path of the folder: Relative to the workspace file.
|
||
|
* - Create a GFile instance of that path, and call open_folder(file: File) and pass the GFile instance to it.
