MindFusion.Virtual Keyboard for WinForms Versionen

Automatic popup extender

• The new VirtualKeyboardExtender component provides declarative virtual keyboard auto-show capabilities for Windows Forms applications. When added to a form, it implements IExtenderProvider to expose design-time properties on all input controls, enabling the virtual keyboard to automatically pop up on focus and hide when focus leaves:
  • AutoShow – enables or disables automatic popup display for the target control (or for all child controls when set on the Form).
  • LayoutMode – specifies the keyboard layout (Default, Extended, Compact, Numeric3x4, or Numeric4x4) associated with the focused control.
  • PopupPlacement – defines the popup position relative to the control (Bottom, Top, Left, Right, FormBottom, or ScreenBottom).
  • CustomLayout – allows assigning a custom KeyboardLayout template to specific fields.
• The popup uses a non-activating tool window style, ensuring that interaction with the virtual keyboard never steals focus from the active text box. Both physical and on-screen keyboard inputs work simultaneously without focus interruptions.

New standard layouts

• Three new built-in keyboard layouts have been added to the KeyboardMode enumeration and can be activated via the Mode property or retrieved as reusable KeyboardLayout templates:
  • Compact – a streamlined layout without function keys (F1–F12) or redundant modifiers, ideal for mobile, touch, and compact popup windows.
  • Numeric3x4 – a 3×4 telephone-style numeric keypad with 0–9 digits, Backspace, and Clear (C).
  • Numeric4x4 – a 4×4 numeric keypad including 0–9, decimal point, minus sign, Backspace, Clear, Tab, and Enter.

Miscellaneous

• Added ClearKey class and static Clear property to clear the contents of currently focused input controls.
• Added ForceUpdateLayout method to VirtualKeyboard.
• Automatic password detection: the auto-show popup automatically enables PasswordMode when the target field is a password box.
