UserInterfaceLabel

Color the control is filled with: the face of a button, the track of a slider, the box of a check box or radio button, the field of a text box, the whole rectangle of a label, icon or grid. Color.Empty, the default, means the control chooses the color for the theme that is in use and follows the theme when it changes. Labels and icons draw no background when this is Color.Empty. A grid fills with the theme's panel color when it is a top level control, and draws no background when it is inside another control. UserInterfaceGrid.BackgroundOpacity makes the theme color see through, or turns the background off at 0.

Does this object have keyboard focus? An object with keyboard focus gets first refusal on what is typed in a viewport; what it does not use carries on to the command line as usual.

Color used to draw the text. Color.Empty, the default, means use the standard text color for the theme that is in use.

Height of the text in logical pixels. A value of 0, the default, means use the standard control font height. Controls that draw no text ignore this setting.

Where the text sits inside the control's rectangle. This is not the same as HorizontalAlignment, which is where the control sits inside its parent.

Where the text sits inside the control's rectangle. This is not the same as VerticalAlignment, which is where the control sits inside its parent.

Text shown in a tooltip when the mouse rests over this object. Null or an empty string means no tooltip, which is what an object starts with. One tooltip is on screen at a time; whichever object the mouse is over owns it.

Make this object visible for all documents. Typically you will only have user interface objects work with single documents. For that case, call doc.ViewUserInterface.Add

Call RunCommand to have the virtual OnRunCommand function executed in the scope of a Rhino command. If you are modifying the document from one of the mouse functions on this object, this is the best approach to do so since changes made inside of a command are recorded for undo.
