DevComponents.DotNetBar.Keyboard

Holds information about a single virtual keyboard Key.

Creates a new Key object.

Returns a string that represents the current Key.

A string that represents the current Key.

Gets the caption on the key.

Gets the actual key-information that is sent to the attached control. The format of this information must confirm to the description for the SendKeys.Send function. For more details, see: http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx

Gets the bounds of the key.

Gets a value representing the way the key looks on the virtual keyboard. A key might look normal, lighter, darker or with a pressed effect.

Gets the index of the layout to change to, if this key is pressed. A positive value represents a new layout. KeyboardLayout.NoChange and KeyboardLayout.PreviousLayout constants can also be used with special meaning.

If this is a positive integer ( >= 0 ), it represents the index of the layout to switch to when this key is pressed. In this case, the keyboard does not send any key information to the attached control (the Info field is ignored), only changes the layout. If this is KeyboardLayout.NoChange the keyboard will send the info to the attached control. If this is KeyboardLayout.PreviousLayout the keyboard will switch to the previous set layout. The keyboard maintains internally a stack of all used layouts. If no more layouts in the stakc, the keyboard switches to the layout with index 0.

Gets the index of the layout to change to, when this key is double clicked. A positive value represents a new layout. KeyboardLayout.NoChange and KeyboardLayout.PreviousLayout constants can also be used with special meaning.

Gets the text that will be displayed in the upper part of the keyboard, as a hint for what the key does, usually in combination with a modifier key (e.g. Underline, Undo, etc).

Specifies the way a key looks, specifically what color it uses from the ColorTable.

Key should be drawn as a normal key colors.

Key should be drawn with lighter colors.

Key should be drawn with darker colors.

Key should be drawn with the pressed color.

Key should be drawn with the toggled color.

Represents a layout for a virtual keyboard.

The Keys have coordinates in the KeyboardLayout specified in logical layout units. By default for this version of the control, a normal key is 10 logical units (LUs) width and 10 LUs height. A space between two keys is 1 LU. When rendering, we assume the whole Layout is stretched over the Keyboard control, so we need to change from LUs (ranging from 0 to layout.LogicalWidth) to pixels (ranging from 0 to control.Width). This allows the layout to be resized to almost any sizes.

Indicates that a key should switch the Keyboard to the previous layout.

Indicates that a key does not switch to any layout.

Tests if a certain point hits a key on the virtual keyboard.

The x-coordinate of the hit point (in logical units of this KeyboardLayout) The y-coordinate of the hit point (in logical units of this KeyboardLayout) Returns the key that was hit, or null if the point didn't hit any keys.

Gets the collection of the Keys in this KeyboardLayout.

Gets the logical width of this KeyboardLayout.

Gets the logical height of this KeyboardLayout.

Represents a layout for a virtual keyboard in which keys are defined in a linear way. This class allows creation of layouts in which keys can be ordered from left to right and from top to bottom.

With the linear layout, the keys are allowed to have any width. The height, however, must be the same. This layout is build by adding to it spaces, keys and new lines. A key represents a virtual key AND a space after it. A space represents a placeholder between two keys and it is used when there is need for a larger space between two certain keys A new line represents the fact that a new line of keys should be defined. The default virtual keyboard of the VirtualKeyboard control is defined in the following way:


             AddKey("q");
             AddKey("w");
             AddKey("e");
             // ...
             AddKey("p");
             AddKey("Backspace");
            
             AddLine(); // Starts a new row of keys.
             AddSpace(4); // Creates a larger space at the beginning of the second row.
            
             AddKey("a");
             AddKey("s");
             // ...

The logical size of the space between two keys.

The logical size of a key.

Adds a space to this LinearKeyboardLayout.

The size of the space, in logical units.
