VSCode扩展API - 滚动

Question

Is there a way to detected when scrolling in the VSCode extension API. The only available functions I see are:

onDidChangeActiveTextEditor: Event<TextEditor>

onDidChangeTextEditorOptions: Event<TextEditorOptionsChangeEvent>

onDidChangeTextEditorSelection: Event<TextEditorSelectionChangeEvent>

onDidChangeTextEditorViewColumn: Event<TextEditorViewColumnChangeEvent>

onDidChangeVisibleTextEditors: Event<TextEditor[]>

onDidChangeWindowState: Event<WindowState>

onDidCloseTerminal: Event<Terminal>

I can file this as a feature request. But is there any way to circumvent this behavior?

Answer 1

VS Code now has an api for this: window.onDidChangeTextEditorVisibleRanges

This event is fired with an TextEditorVisibleRangesChangeEvent object:

export interface TextEditorVisibleRangesChangeEvent {
    /**
     * The text editor for which the visible ranges have changed.
     */
    textEditor: TextEditor;

    /**
     * The new value for the text editor's visible ranges.
     */
    visibleRanges: Range[];
}

VS Code's markdown preview uses this event to synchronize the scrolling of the editor with the markdown preview.
