示例1: focusTree
private focusTree(): void {
if (!this.tree) {
return; // return early if viewlet has not yet been created
}
// Make sure the current selected element is revealed
const selection = this.tree.getSelection();
if (selection.length > 0) {
this.reveal(selection[0], 0.5).done(null, errors.onUnexpectedError);
}
// Pass Focus to Viewer
this.tree.domFocus();
}示例2: onLeftClick
protected onLeftClick(tree: ITree, element: any, event: IMouseEvent, origin: string = 'mouse'): boolean {
// In file browser, double clicking an element calls tree.dispose(). There should not be any tree events after selection.
if (event.detail === 2) {
var payload = { origin: origin, originalEvent: event };
if (tree.getInput() === element) {
tree.clearFocus(payload);
tree.clearSelection(payload);
} else {
var isMouseDown = event && event.browserEvent && event.browserEvent.type === 'mousedown';
if (!isMouseDown) {
event.preventDefault(); // we cannot preventDefault onMouseDown because this would break DND otherwise
}
event.stopPropagation();
tree.domFocus();
tree.setSelection([element], payload);
}
return true;
} else {
return super.onLeftClick(tree, element, event, origin);
}
