Description

Value	Description
ietxCenterThumbnailColumn	If enabled and one or more columns are displayed (i.e. GridWidth <> 0) then the thumbnails will be centered horizontally in the view (but not vertically centered).If enabled and only one row is displayed (i.e. GridWidth = 0) then the thumbnails will be centered vertically in the view (but not horizontally centered).When not enabled, the top-left thumbnail will always be at a distance of HorizBorder x VertBorder from the corner.
ietxShowIconForUnknownFormat	If enabled, then for any ImageFileName of an unknown format ImageEn will load the default icon for that file type (retrieved from Windows using the ShGetFileInfo Shell API function). Otherwise a question mark is displayed.Note: Don't disable this option if you are showing folders
ietxShowIconWhileLoading	If enabled, then the default icon for each file type is displayed while the content is loaded (retrieved from Windows using the ShGetFileInfo Shell API function). Otherwise a blank thumbnail is displayed.
ietxShowShadowForIcons	If SoftShadow is enabled, then this option determines whether the shadow is displayed for file icons
ietxShowShadowForFolders	If SoftShadow is enabled, then this option determines whether the shadow is displayed for folder icons
ietxEnableInternalIcons	If ietxShowIconWhileLoading is not specified, then while loading either a blank or internal icon will be displayed (can be set with DefaultFileIcon). Also, when specified an internal icon is shown for files that cannot be found(can be set with MissingFileIcon).
ietxStretchSmallImages	If specified, images smaller than the thumbnail cell will be stretched (resampled) to the size of other thumbnail images. If not specified, small images shown at 100% size.
ietxOnlyShowIcons	Disables image thumbnails and only shows file icons (even for supported image types).
ietxFillWithImgBackground	If enabled, the background color of the thumbnail will be filled with that of the image. Otherwise it is set to ThumbnailsBackground.
ietxDrawTextFullWidth	If enabled, and a solid background has been specified for the text, the background color will fill the width of the thumbnail (otherwise the background color is only as wide as the text).

Examples

// Use icons for unknown files
ImageEnMView1.ThumbnailOptionsEx := ImageEnMView1.ThumbnailOptionsEx + [ietxShowIconForUnknownFormat];

// Display all files (not only image files)
ImageEnMView1.FillFromDirectory('C:\', -1, true);

// Do not show shadows for any icon types
ImageEnMView1.ThumbnailOptionsEx := ImageEnMView1.ThumbnailOptionsEx - [ietxShowShadowForIcons, ietxShowShadowForFolders];

// Redraw the display
ImageEnMView1.Update();

// Create a single column of centered thumbnails
ImageEnMView1.GridWidth := 1;
ImageEnMView1.ThumbnailOptionsEx := ImageEnMView1.ThumbnailOptionsEx + [ietxCenterThumbnailColumn];
ImageEnMView1.Update();

// Show file list with icons
ImageEnMView1.ThumbnailOptionsEx := ImageEnMView1.ThumbnailOptionsEx + [ ietxOnlyShowIcons ];

// Give Thumbnail text a solid yellow background to the width of the thumbnail
ImageEnMView1.TextBackgroundStyle := bsSolid;
ImageEnMView1.TextBackgroundColor := clYellow;
ImageEnMView1.ThumbnailOptionsEx := ImageEnMView1.ThumbnailOptionsEx + [ietxDrawTextFullWidth];
