Property List

Enabled
Controls the item enabled state. Setting the enabled state of an item to false will also disable items or their contents. (Read/Write boolean)
FixedHeight
The fixed height of the item in pixels. When the fixed height is set to a positive value, it is the height of the item. Setting the fixed height to zero or a negative value will restore the default/auto setting and the height will be dynamically determined. The fixed height takes precedence over the minimum height and thus the minimum height is ignored when a fixed height is set. (Read/Write number)
FixedWidth
The fixed width of the item in pixels. When the fixed width is set to a positive value, it is the width of the item. Setting the fixed width to zero or a negative value will restore the default/auto setting and the width will be dynamically determined. The fixed width takes precedence over the minimum width and thus the minimum width is ignored when a fixed width is set. (Read/Write number)
IconPath
The icon of the push button. (Read/Write string)
ItemHeight
The height of the item in pixels. (Read only number)
ItemWidth
The width of the item in pixels. (Read only number)
Label
The label of the push button. (Read/Write string)
MinimumHeight
The minimum height of the item in pixels. When the height is dynamically determined, it will not be less than the minimum height setting. The minimum height value will only be used when the FixedWidth is not set (restored to the default/auto setting). Setting the minimum height to zero or a negative value will restore the default/auto setting where no minimum height is enforced. (Read/Write number)
MinimumWidth
The minimum width of the item in pixels. When the width is dynamically determined, it will not be less than the minimum width setting. The minimum width value will only be used when the FixedWidth is not set (restored to the default/auto setting). Setting the minimum width to zero or a negative value will restore the default/auto setting where no minimum width is enforced. (Read/Write number)
