Text Control

The Text control displays static text, which may use a predefined style.

The recommended method for displaying text with specified line breaks is to use multiple one-line text controls located below each other. The character sequences \n, \r\n, or \n\r in the text field for the control are not displayed as a line break. These character sequences are literally displayed by the control.

Control Attributes

You can use the following attributes with the Text control. To change the value of an attribute using an event, subscribe the control to a ControlEvent in the EventMapping table and list the attribute's identifier in the Attribute column. Enter the identifier of the ControlEvent in the Event column.

Attribute identifierHexadecimal bitDescription
Position Position of control in the dialog box.

Enter the control's width, height, and coordinates of the control's left corner into the Width, Height, X, and Y columns of the Control table or BBControl table. Use installer units for length and distance.

Text Text displayed by the control.

To set the font and font style of a text string, prefix the string of displayed characters with {\style} or {&style}. Where style is an identifier listed in the TextStyle column of the TextStyle table. If neither of these are present, but the DefaultUIFont property is defined as a valid text style, that font will be used.

TimeRemaining This attribute enables a Text control to display the approximate number of minutes and seconds remaining for an installation.

Subscribe the Text control to the TimeRemaining ControlEvent in the Eventmapping table and enter TimeRemaining into the Attribute column.

The installer publishes a record containing one integer representing the number of seconds remaining in the installation. Include a row in the UIText table with TimeRemaining in the Key column. Enter a formatted text string into the Text column authored to display minutes and seconds. Format this string as described for MsiFormatRecord.

If this bit is set the control attempts to format the displayed text as a number representing a count of bytes. For proper formatting, the control's text must be set to a string representing a number expressed in units of 512 bytes. The displayed value will then be formatted in terms of kilobytes (KB), megabytes (MB), or gigabytes (GB), and displayed with the appropriate string representing the units.

 

Remarks

This control can be created from the STATIC class by using the CreateWindowEx function. It has the SS_LEFT, WS_CHILD, and WS_GROUP styles.

Do not place transparent Text controls on top of colored bitmaps. The text may not be visible if the user changes the display color scheme. For example, text may become invisible if the user sets the high contrast parameter for accessibility reasons.
