For instance:
- "`[debug]` + menu" displays all item's identifiers in the control's default menu
- "menu replace `&Delete` with ``" removes the Delete command from any context menu
- "Popup(Item 1[id=1001],Item 2[id=1002],Item 3[id=1003]),[sep],Exit[def][id=1000]" defines a popup, a separator and a default item. This context menu will be shown any time, no mater if none, one or more files are selected
- "filecount > 1 ? `multiple selection[dis]` : menu" displays "multiple selection" displays the default context menu if the user selected a single file, else invokes the context menu for multiple-items selection
- "`Popup(Item 1[id=1001],Item 2[id=1002],Item 3[id=1003]),` + menu + `,Exit[id=1000]`" combine's the default selection context menu, so Popup is displayed at the top of the context menu, and the Exit item at the bottom. The Popup and Exit are always displayed, while the control's selection default context menu are shown only if available.
- "filecount = 0 ? `Popup(Item 1[id=1001],Item 2[id=1002],Item 3[id=1003]),[sep],Exit[def][id=1000]` : menu" defines a separated context menu when no file/folder is selected ( control's background context menu ). The default context menu is shown if the user right-clicks a file, folder or the selection.
The ShowContextMenu property supports the following predefined keywords:
- menu keyword returns a string expression that defines the shell context menu's tostring representation
- filecount keywords returns a numeric expression that specifies the number of items/files/folders selected in the control
- fileattr keyword returns a numeric expression that specifies the attributes of the single-selected item in the control ( the keyword's value is valid while the filecount property is 1)
- filename keyword returns a string expression that specifies the name of the single-selected item in the control ( the keyword's value is valid while the filecount property is 1)
- fileparsename keyword returns a string expression that specifies the parsed name of the single-selected item in the control ( the keyword's value is valid while the filecount property is 1)
- filefullname keyword returns a string expression that specifies the full name of the single-selected item in the control ( the keyword's value is valid while the filecount property is 1)
This property/method supports predefined constants and operators/functions as described here.
The ShowContextMenu property indicates the list of commands to be displayed in the context menu, separated by comma (,). Each command must have an id parameter, that specifies the identifier of the command. Optional parameters are def for default item, and dis for disabled items. The sep parameter indicates a separator item. If adding new items to the object's context menu, use the ExecuteContextMenu property to get the identifier of the command to be executed during the StateChange(ExecuteContextMenu) event
For instance, the ShowContextMenu property on "Item 1[id=1][def],Popup[id=2](Sub-Item 2[id=2],[sep],Sub-Item 3[id=3])" shows the context menu as following:
