Allows you to filter files by filename patterns.
property Filter: UnicodeString;
If soShowFiles is included in the property ShowOptions, you can use this property to filter the displayed files by pattern. You can use a single pattern, e.g. '*.doc' or concatenate several patterns using semicolons to separate them, e.g. '*.exe;*.com'.
Using the following filter, only GIF and JPEG images will appear in the TJamShellList:
JamShellTree.Filter := '*.jpg;*.gif';
