How to apply security to a Menu Item

Adding security to a Menu Item

To control access to menu items based on user roles and permissions, Servoy provides a permissions property that enables security configurations. Follow the steps below to apply security settings to a menu item:

1. Open the Properties Panel

   • Select the Menu Item you want to secure in Solution Explorer.

   • Open the Properties panel to view the menu item’s attributes.

2. Locate the permissions property

   • In the Properties panel, find the permissions field under the Global Properties section.

   • Click on the field to open the permissions configuration dialog.

3. Configure Security Settings

   • The permissions dialog allows you to define which roles can view or enable the menu item.

   • Add or modify roles by selecting them from the available list.

4. Set Visibility and Access

   • Visible: Determines whether the menu item is displayed for a given user role.

   • Enabled: Controls whether the menu item is interactive or disabled for specific roles.

5. Apply and Save Changes

   • Click OK to confirm the security settings.

   • Save your changes to ensure that the menu item follows the configured access restrictions.

Security Options:

• Visible: If a menu item is not visible, users assigned to the restricted role will not see it in the application.

• Enabled: If a menu item is disabled, users with restricted permissions will see the menu item, but it will be inactive (grayed out or unclickable).

This method ensures that menu items are accessible only to authorized users, improving security and user experience.

Scripting a Menu

The Servoy Menu API enables developers to create, modify, and manage menus dynamically through scripting. Using the JSMenu object, you can define menu structures, add or remove menu items, retrieve existing menus, and control their behavior at runtime.

Here are some examples:

Creating and Managing Menus:

Create a New Menu

Method: menus.createMenu(name) Use Case: When dynamically creating a menu at runtime for different user roles or application states.

Example: Creating a menu named mainMenu:

var myMenu = menus.createMenu('mainMenu');

This menu can now be modified by adding items and configuring properties.

Retrieve an Existing Menu

Method: menus.getMenu(name) Use Case: When needing to modify an existing menu that was created at design time or earlier in runtime.

Example: Retrieving a menu named mainMenu:

var existingMenu = menus.getMenu('mainMenu');
if (existingMenu) {
    application.output('Menu found!');
} else {
    application.output('Menu not found.');
}

If the menu exists, it can be modified; otherwise, a new menu may need to be created.

Retrieve All Menus

• Method: menus.getMenus()

• Use Case: When listing or managing all available menus in an application.

Example: Listing all available menus:

var allMenus = menus.getMenus();
for (var i = 0; i < allMenus.length; i++) {
    application.output(allMenus[i].name);
}

This is useful for dynamically managing different menus based on application state.

---

Working with Menu Items:

Add a Menu Item

• Method: JSMenu.addMenuItem(id) or JSMenu.addMenuItem(id, index)

• Use Case: When adding new menu items dynamically at the end of the menu or at a specific position.

Example: Adding a new item dashboard at the end of the menu:

var myMenu = menus.getMenu('mainMenu');
var menuItem = myMenu.addMenuItem('dashboard');
menuItem.menuText = "Dashboard";

Adding an item reports at a specific position:

var myMenu = menus.getMenu('mainMenu');
var menuItem = myMenu.addMenuItem('reports', 1);
menuItem.menuText = "Reports";

This allows menu structures to be dynamically modified at runtime.

Retrieve a Menu Item by ID

• Method: JSMenu.getMenuItem(id)

• Use Case: When modifying properties of an existing menu item.

Example: Finding and modifying the dashboard menu item:

var myMenu = menus.getMenu('mainMenu');
var item = myMenu.getMenuItem('dashboard');
if (item) {
    item.menuText = "Dashboard Home";
}

This is useful for dynamically changing menu item labels.

Find a Menu Item (Including Nested Ones)

• Method: JSMenu.findMenuItem(id)

• Use Case: When searching for a menu item that may be deeply nested.

Example: Finding the settings menu item in a multi-level menu:

var myMenu = menus.getMenu('mainMenu');
var nestedItem = myMenu.findMenuItem('settings');
if (nestedItem) {
    application.output('Found settings menu!');
}

This helps when working with hierarchical menus.

Retrieve a Menu Item by Index

• Method: JSMenu.getMenuItemAt(index)

• Use Case: When looping through menu items sequentially.

Example: Getting the first menu item:

var myMenu = menus.getMenu('mainMenu');
var firstItem = myMenu.getMenuItemAt(0);
application.output(firstItem.text);

This can be useful when processing menu items dynamically.

Retrieve All Menu Items

• Method: JSMenu.getMenuItems()

• Use Case: When iterating over all menu items to apply changes or log data.

Example: Listing all menu items:

var myMenu = menus.getMenu('mainMenu');
var menuItems = myMenu.getMenuItems();
for (var i = 0; i < menuItems.length; i++) {
    application.output(menuItems[i].text);
}

This is helpful for bulk operations on menu items.

---

Removing and Selecting Menu Items:

Remove a Menu Item

• Method: JSMenu.removeMenuItem(menuItem) or JSMenu.removeMenuItem(id)

• Use Case: When dynamically updating menus based on conditions such as user permissions.

Example: Removing a menu item by reference:

var myMenu = menus.getMenu('mainMenu');
var menuItem = myMenu.getMenuItem('dashboard');
if (menuItem) {
    var success = myMenu.removeMenuItem(menuItem);
    application.output(success ? 'Item removed' : 'Failed to remove');
}

Removing a menu item by ID:

var myMenu = menus.getMenu('mainMenu');
var success = myMenu.removeMenuItem('reports');
application.output(success ? 'Reports removed' : 'Reports not found');

This helps keep menus relevant to user roles.

Select a Menu Item

• Method: JSMenu.selectMenuItem(menuItem)

• Use Case: When highlighting a specific menu item based on user navigation.

Example: Selecting the dashboard item:

var myMenu = menus.getMenu('mainMenu');
var menuItem = myMenu.getMenuItem('dashboard');
if (menuItem) {
    myMenu.selectMenuItem(menuItem);
}

This can be useful for guiding users through workflows.

Get the Selected Menu Item

• Method: JSMenu.getSelectedItem()

• Use Case: When tracking user selections to trigger events.

Example: Getting the currently selected menu item:

var myMenu = menus.getMenu('mainMenu');
var selectedItem = myMenu.getSelectedItem();
if (selectedItem) {
    application.output('Current selection: ' + selectedItem.text);
}

This is useful for building dynamic interfaces that respond to user actions.

---

Security and Menu Items

Retrieve Menu Items with Security Considerations

• Method: JSMenu.getMenuItemsWithSecurity()

• Use Case: When fetching only menu items that the user has permission to view.

Example: Getting all accessible menu items:

var myMenu = menus.getMenu('mainMenu');
var secureItems = myMenu.getMenuItemsWithSecurity();
for (var i = 0; i < secureItems.length; i++) {
    application.output('Accessible: ' + secureItems[i].menuText);
}

This method ensures that restricted items are not exposed to unauthorized users.

Scripting a Menu Item

The JSMenuItem API in Servoy allows developers to dynamically create, configure, and manage individual menu items. With its built-in methods, menu items can be customized with security settings, dynamically modified, or linked to specific application behaviors.
