Description

This class is a package of instructions related to the application user interface (UI). It includes the ability to bridge communication between plugins and the application UI system, provides operations for the main window and menu, application version settings, show message boxes, open file browse dialog, as well as adding RIDialog and RIDockWidget related components, and much more. By using this class, developers can define plugin behaviors via custom user interfaces to achieve their goals.

Member Functions

GetMainWindow ( self )

Get the QWidget address for the main window. You can bind the main window to a PySide object by using this function, for UI operations.

Returns

QWidget address for the main window - QWidget address

1 # Get MainWindow QWidget address
2 main_widget = wrapInstance(int(RLPy.RUi.GetMainWindow()), PySide2.QtWidgets.QWidget)

AddMenu ( self, strMenuName, eParent )

Currently, this function can only create menu items within the Plugins menu. The Qmenu address is returned upon creation.

Parameters

strMenuName [IN] The desired menu item name - string

eParent [IN] The parent menu for this menu item - RLPy.EMenu

Returns

The QMenu address for the newly created menu item - QMenu address

1 # Add menu item to Plugins menu
2 menu_item = "TestMenu"
3 menu_address = RLPy.RUi.AddMenu(menu_item, RLPy.EMenu_Plugins)
4 print(menu_address)
5 
6 # add Test menu
7 plugin_menu = wrapInstance(int(RLPy.RUi.AddMenu("Test", RLPy.EMenu_Plugins)), PySide2.QtWidgets.QMenu)
8 plugin_action = plugin_menu.addAction("sub menu action")
9 plugin_action.triggered.connect(do_somthing)

RemoveMenu ( self, pMenu )

Remove a menu item from the main window. Currently, this function only supports removal of menu items from the Plugins menu.

Parameters

pMenu [IN] Menu item address for removal - QMenu address

Return

Success - RLPy.RStatus.Success

Failure - RLPy.RStatus.Failure

1 # Remove menu item from Plugins menu
2 menu_item = "TestMenu"
3 menu_address = RLPy.RUi.AddMenu(menu_item, RLPy.EMenu_Plugins)
4 result = RLPy.RUi.RemoveMenu(menu_address)
5 print(result)

AddHotKey ( self, strKeySequence )

Create and register a hotkey event. The input hotkey string will be compared with the keys within QKeySequence of the Qt component and returns a QAction address. If the given hotkey is already registered to another event, then the previous event will be replaced by the newly registered hotkey event. In order to revert to the previous event, one must first unregister the current event.

Parameters

strKeySequence [IN] The desired hot key name, to be compared to the keys in the QKeySequence of the Qt component - string

Returns

The QAction address for the newly created hotkey - QAction address

 1 import PySide2
 2 from PySide2.QtWidgets import QWidget
 3 from PySide2.shiboken2 import wrapInstance
 4 
 5 # Define global function
 6 def do_space_action():
 7     print("Space action start.")
 8 
 9 # Add hot key to trigger action
10 space_action = wrapInstance(int(RLPy.RUi.AddHotKey("Space")), PySide2.QtWidgets.QAction)
11 space_action.triggered.connect(do_space_action)
12 
13 # Add hot key(combo key) to trigger action
14 space_action = wrapInstance(int(RLPy.RUi.AddHotKey("Ctrl+G")), PySide2.QtWidgets.QAction)
15 space_action.triggered.connect(do_space_action)

RemoveHotKey ( self, pAction )

Remove a hotkey event registered to the given QAction address.

Parameters

pAction [IN] The QAction address of the hotkey designated for removal - QAction address

Return

Success - RLPy.RStatus.Success

Failure - RLPy.RStatus.Failure

GetResolutionType ( self )

Get the application resolution settings.

Returns

The current application resolution mode - RLPy.EResolutionType

3 print(resolusion_type)

GetCSSType ( self )

Get the current application cascading style sheet (CSS) settings.

Returns

Application CSS settings - RLPy.ECSSType

1 # Get CSS type
2 css_type = RLPy.RUi.GetCSSType()
3 print(css_type)

ShowMessage ( self, strTitle, strMsg, eBtn, bChecked, strCheckBoxMsg )

Display a message box on the screen. The title, text content, and button options are configurable. Bitwise operations can be applied to combine different button types. The message box can also be set to contain a checkbox and a message to go with it. Developers can configure the appropriate response for the RLPy.EMsgButton enum return value. Activated checkboxes in the message box can be intercepted with the RLPy.EMsgButton_Ok return value.

See Also: RLPy.EMsgButton

Parameters

strTitle [IN] MessageBox title name - string

strMsg [IN] MessageBox message - string

eBtn [IN] MessageBox button options (Use bitwise operators to combine different types of buttons) - RLPy.EMsgButton

bChecked [IN] Whether to show a checkbox. Once it is present, its check state is also determined by this parameter - boolean

strCheckBoxMsg [IN] The message accompanies the checkbox - string

Returns

The integer value of this user interface's RLPy.EMsgButton - integer
