Constructors
View SourceInputMethodContext()
Constructor.
Declaration
public InputMethodContext()
Methods
View SourceActivate()
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()
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. |
Deactivate()
Deactivates the IMF.
It means that the text editing is complete.
Declaration
public void Deactivate()
DestroyContext()
Destroys the context of the IMF.
Declaration
public void DestroyContext()
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. |
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. |
GetInputPanelLocale()
Gets the current language locale of the input panel.
For example, en_US, en_GB, en_PH, fr_FR, and so on.
Declaration
public string GetInputPanelLocale()
Returns
Type | Description |
---|---|
string | The current language locale of the input panel. |
GetInputPanelState()

Declaration
public InputMethodContext.State GetInputPanelState()
Returns
Type | Description |
---|---|
InputMethodContext.State | The state of the input panel. |
GetInputPanelUserData(out string)
Gets the specific data of the current active input panel.
Declaration
public void GetInputPanelUserData(out string text)
Parameters
Type | Name | Description |
---|---|---|
string | text | The specific data to be received from the input panel. |
GetKeyboardType()

Declaration
public string GetSurroundingText()
Returns
Type | Description |
---|---|
string | The surrounding text. |
GetTextDirection()
Returns the text direction of the current input language of the keyboard.
Declaration
