Constructors

InputMethodContext()

Constructor.

Declaration

public InputMethodContext()

Methods

View Source

Activate()

Activates the IMF.
It means that the text editing has started.
If the hardware keyboard is not connected, then it shows the virtual keyboard.

Declaration

public void Activate()

View Source

AutoEnableInputPanel(bool)

Enables to show the input panel automatically when focused.

Declaration

public void AutoEnableInputPanel(bool enabled)

Parameters

Type	Name	Description
bool	enabled	If true, the input panel will be shown when focused.

View Source

Deactivate()

Deactivates the IMF.
It means that the text editing is complete.

Declaration

public void Deactivate()

View Source

DestroyContext()

Destroys the context of the IMF.

Declaration

public void DestroyContext()

View Source

GetCursorPosition()

Gets the cursor position stored in VirtualKeyboard, this is required by the IMF context.

Declaration

public uint GetCursorPosition()

Returns

Type	Description
uint	The current position of the cursor.

View Source

GetInputMethodArea()

Provides the size and the position of the keyboard.
The position is relative to whether the keyboard is visible or not.
If the keyboard is not visible, then the position will be off the screen.
If the keyboard is not being shown when this method is called, the keyboard is partially setup (IMFContext) to get/> the values then taken down. So ideally, GetInputMethodArea() must be called after Show().

Declaration

public Rectangle GetInputMethodArea()

Returns

Type	Description
Rectangle	Rectangle which is keyboard panel x, y, width, and height.

View Source

GetInputPanelLocale()

Gets the current language locale of the input panel.
For example, en_US, en_GB, en_PH, fr_FR, and so on.
