Optional name for the control. If the ThmUtil variable callback system has been configured, such as by WixStandardBootstrapperApplication, ThmUtil uses the control name to find a matching variable name. ThmUtil retrieves the variable's value to set the initial value of the control and sets the variable's value when the user interacts with the control. For example, a checkbox control is checked when the matching variable has a nonzero value and unchecked for a value of `0`. When the user checks a checkbox control, ThmUtil sets the variable value to a nonzero value (currently `1`) and to `0` if the checkbox is unchecked. An edit box control gets its initial value from a matching variable value. The control value is saved to the variable when navigating away from the page or when choosing a folder via an associated Browse button. A condition that determines if the control is enabled. If this condition is true or omitted, then the control will be enabled. Height of the control. Non-positive values extend the control to the bottom of the window minus the value. A zero value extends the control to the bottom of the window. Hexadecimal window style for the control. Specifies whether the control should be hidden when disabled. Specifies whether the control is part of the tab sequence of controls. Specifies whether the control is initially visible. A condition that determines if the control is visible. If this condition is true or omitted, then the control will be visible. Width of the control. Non-positive values extend the control to the right of the window minus the value. A zero value extends the control to the right of the window. X coordinate for the control from the left of the window. Negative values are coordinates from the right of the window minus the width of the control. Y coordinate for the control from the top of the window. Negative values are coordinates from the bottom of the window minus the height of the control.
