You can use the RichText edit style to display column data in a rich text format, and to use different fonts and colors in the same data field.
Columns that you format with the RichText edit style require considerably more storage space than columns with plain text edit styles. Therefore you should set a minimum of 1 KB for the column width. Otherwise, you can use the RichText edit style with columns that have large text datatypes.
Maximum text length By default, the maximum text length for a DataWindow column is 32 KB. However, for most database drivers, you can set this length to a higher value. For the PowerBuilder ODBC driver, you can set the maximum text length in the pbodbxxx.ini file, where xxx is the PowerBuilder version number. If you add "PBMaxTextSize=1024000" to the section of the INI file for the database to which you are connecting, you change the maximum text length for a DataWindow column to 1 MB.
By default, whenever a column with the RichText edit style is edited in the Preview view or at runtime, a font toolbar displays. The font toolbar disappears when the column loses focus. The following picture shows the default font toolbar available for columns with the RichText edit style:
You can modify the RichTextToolbarActivation constant on a DataWindow control to display the font toolbar whenever a DataWindow object containing columns with the RichText edit style has focus—whether or not this type of column is selected. You can also modify the constant so that the font toolbar never appears.
For more information, see RichTextToolbarActivation in the online Help.
The RichText edit style is not available for columns in a DataWindow object with the Graph, OLE, or RichText presentation styles.
