UserInterfaceRadioButton Properties

Is this the button that is on in its group? Turning a button on turns off every other button in its group. Setting this does not raise CheckedChanged; that is only for a state the user changed.

The button in this button's group that is on, which can be this button, or null when nothing in the group has been turned on yet. The buttons have to have been added to a document for this to find anything, since it is the native side that keeps track of a group.

Which set of radio buttons this one belongs to. The default is 0. Two sets of radio buttons in the same container need different group numbers or they will turn each other off.

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.

3d location that control "sticks" to if not null

Is the user interface object visible? Objects that are not visible will not be drawn and will not receive mouse events
