TImageEnMView.ThumbWidth

Declaration

property ThumbWidth: Integer;

Description

Specifies the width of the thumbnails displayed in the TImageEnMView.
If ThumbWidth < 0, then the thumbnail width is automatically calculated to fit that number of columns, e.g. ThumbWidth = -1, the thumbnails will be the width of the control, -2, there will be two columns of thumbnails, etc.

Note: This is the width of the thumbnail frame (when the Style is iemsFlat). The thumbnail image itself will be ThumbWidth less LeftGap and RightGap . See ThumbSizeInfo for actual display size. Use SetThumbnailSize to set the display size of the image itself.

TImageEnMView Default: 100;
TImageEnFolderMView Default: 130
TImageEnLayerMView Default: 120
