Property Page Controls

Most controls are typically inherently tied to the data type of the associated parameter. For example, a check box is the default control for a boolean parameter and a numeric control (normally with both an edit control and a slider) is the default control for any numeric parameter.

There are also alternate controls, like the icon list control, which functions like a radio control but displays a bitmap icon instead of the radio button. Another example is the list box and combo (drop-down) box controls which both offer a set of choices to the user but one (list box) is more suited to short lists than the other (combo box).

The command button control is not directly associated with a parameter. In this case, a function in the underlying logic is executed when the user clicks the button. This function may perform tasks using the parameter data from the associated property set.

The various controls available on the Property Page Layout or Property Page Layout are summarized in the following table. The Name column contains links to more specific information about the control, including which attributes it supports:

Name	Category	Data Type	Default	Description	siPPGControlType value
Static Text	Labels	string		Displays value of a string parameter as read-only. This can be used to add instructions to a Property Page.	siControlStatic
Bitmap Widget	Labels	anything		Generally used for displaying bitmap (icon or logo), this control is associated with a real parameter on the underlying CustomProperty but the value is neither read nor changed.	siControlBitmap
Single-line Text	Editable Text Boxes	string	yes	Editable text box; default control for a string parameter.	siControlString

Combo/Drop-Down Box	Enum Controls	string or numeric (integers, longs, floats and doubles)		Lists a number of options (read-only values) with only the selected item visible; user clicks on control to display all possible items to choose from; well-suited for large lists.	siControlCombo

Bitfield	Enum Controls	numeric (integers, longs, floats and doubles)		Set of small squares indicating whether or not the underlying value is added to the total for the control; user clicks the control to toggle between true and false.	siControlCheck
File Browser Widget	Path Controls	string		Edit box for string path of file and widget for calling the File Browser to pick a file.	siControlFilePath
Folder Widget	Path Controls	string		Edit box for string path of folder and widget for calling the Folder Picker to pick a directory.	siControlFolder
