If the selection is returned in a non-string format, such as INTEGER or ATOM, the selection command converts it to string format as a collection of fields separated by spaces: atoms are converted to their textual names, and anything else is converted to hexadecimal integers.

(this format is different than the selection type see the ICCCM for all the confusing details). The selection owner may choose to return the selection in any of several different representation formats, such as STRING, UTF8_STRING, ATOM, INTEGER, etc.

Type specifies the form in which the selection is to be returned (the desired “target” for conversion, in ICCCM terminology), and should be an atom name such as STRING or FILE_NAME see the Inter-Client Communication Conventions Manual for complete details. Selection defaults to PRIMARY and window defaults to “.”. Retrieves the value of selection from window's display and returns it as a result.

package.json Contributionįirst you have to let VS Code know that you are contributing a view, using the contributes.views Contribution Point in package.json. You can find the complete source code of this sample extension in the tree-view-sample in the vscode-extension-samples GitHub repository. The steps for adding a treeview are to contribute the treeview in your package.json, create a TreeDataProvider, and register the TreeDataProvider.

This extension will use a treeview to display all Node.js dependencies in the current folder. To explain the Tree View API, we are going to build a sample extension called Node Dependencies.

This guide teaches you how to write an extension that contributes Tree Views and View Containers to Visual Studio Code.

The Find All References results are displayed in a References: Results Tree View, which is in the References View Container. Using time.sleep would freeze the mainloop, so you should use the after tkinter method: tree.after(, callback, args) will wait for the given time and then execute callback(args).

This content is structured as a tree and conforms to the style of the built-in views of VS Code.įor example, the built-in References Search View extension shows reference search results as a separate view. The Tree View API allows extensions to show content in the sidebar in Visual Studio Code.
