Context Menu Quick Reference
This guide provides a quick overview of how to create and display a context menu using our system.
ContextMenuItem Type
Define each menu item using the ContextMenuItem type:
type ContextMenuItem = {
label?: string;
type?: "separator" | "normal" | "submenu" | "checkbox" | "radio";
role?: string; // Electron role (optional)
click?: () => void; // Callback for item selection (not needed if role is set)
submenu?: ContextMenuItem[]; // For nested menus
checked?: boolean; // For checkbox or radio items
visible?: boolean;
enabled?: boolean;
sublabel?: string;
};
Import and Show the Menu
Import the context menu module:
import { ContextMenuModel } from "@/app/store/contextmenu";
To display the context menu, call:
ContextMenuModel.getInstance().showContextMenu(menu, event);
- menu: An array of
ContextMenuItem. - event: The mouse event that triggered the context menu (typically from an onContextMenu handler).
Basic Example
A simple context menu with a separator:
const menu: ContextMenuItem[] = [
{
label: "New File",
click: () => {
/* create a new file */
},
},
{
label: "New Folder",
click: () => {
/* create a new folder */
},
},
{ type: "separator" },
{
label: "Rename",
click: () => {
/* rename item */
},
},
];
ContextMenuModel.getInstance().showContextMenu(menu, e);
Example with Submenu and Checkboxes
Toggle settings using a submenu with checkbox items:
const isClearOnStart = true; // Example setting
const menu: ContextMenuItem[] = [
{
label: "Clear Output On Restart",
submenu: [
{
label: "On",
type: "checkbox",
checked: isClearOnStart,
click: () => {
// Set the config to enable clear on restart
},
},
{
label: "Off",
type: "checkbox",
checked: !isClearOnStart,
click: () => {
// Set the config to disable clear on restart
},
},
],
},
];
ContextMenuModel.getInstance().showContextMenu(menu, e);
Editing a Config File Example
Open a configuration file (e.g., widgets.json) in preview mode:
{
label: "Edit widgets.json",
click: () => {
fireAndForget(async () => {
const path = `${getApi().getConfigDir()}/widgets.json`;
const blockDef: BlockDef = {
meta: { view: "preview", file: path },
};
await createBlock(blockDef, false, true);
});
},
}
Summary
- Menu Definition: Use the
ContextMenuItemtype. - Actions: Use
clickfor actions; usesubmenufor nested options. - Separators: Use
type: "separator"to group items. - Toggles: Use
type: "checkbox"or"radio"with thecheckedproperty. - Displaying: Use
ContextMenuModel.getInstance().showContextMenu(menu, event)to render the menu.
Common Use Cases
File/Folder Operations
Context menus are commonly used for file operations like creating, renaming, and deleting files or folders.
Settings Toggles
Use checkbox menu items to toggle settings on and off, with the checked property reflecting the current state.
Nested Options
Use submenu to organize related options hierarchically, keeping the top-level menu clean and organized.
Conditional Items
Use the visible and enabled properties to dynamically show or disable menu items based on the current state.
