| AddMask | ( | description, masks | ) | |
| mask string |
| AddMask | Adds file masks to the file dialog's List Files of Type drop-down list. |
| description | A string constant, variable, EQUATE, or expression that contains a file mask description such as 'all files-*.*' or 'source files-*.inc;*.clw'. The mask value may be included in the description for information only. |
| masks | A string constant, variable, EQUATE, or expression that defines the file mask or masks corresponding to the description, such as '*.*' or '*.inc;*.clw'. Multiple masks are separated by a semi-colon (;). |
| mask string | A string constant, variable, EQUATE, or expression that defines both the file masks and their descriptions. |
The AddMask method adds file masks and their descriptions to the file dialog's List Files of Type drop-down list. The first mask is the default selection in the file dialog.
The SetMask method replaces file masks and their descriptions.
The mask string parameter must contain one or more descriptions followed by their corresponding file masks in the form description|masks|description|masks. All elements in the string must be delimited by the vertical bar (|). For example, 'all files *.*|*.*|Clarion source *.clw;*.inc|*.clw;*.inc' defines two selections for the File Dialog's List Files of Type drop-down list.See the extensions parameter to the FILEDIALOG function in the Language Reference for more information.
Example:
FileMask CSTRING('Text *.txt|*.txt|All *.*|*.*') !File dialog file masks
