Description
Fills the ImageEnMView with files from the specified
Directory. For each file
ImageFileName will be set with the full path and
ImageBottomText with the filename.
You can cancel the insertion of files by setting MIO.Aborting := True;
Parameter | Description | Default |
Directory | The folder to search for files | Required |
FileTypes | Specify the types of files to include | |
Limit | The maximum number of images to load. Use -1 to retrieve all files | -1 |
AllowUnknownFormats | If false (default) only known and supported file formats are loaded. Otherwise all files are loaded | False |
ExcludeExtensions | A comma separated list of file extensions to skip (e.g. 'lyr,all,iev') | '' |
DetectFileFormat | If true then the image type is detected by reading the header (which can be slow). Otherwise ImageEn only checks the file extension | False |
FilterMask | Limits the fill to file extensions found in a comma separated list (e.g. 'jpg,jpeg,jpe'). Specify an empty string to return all supported extensions | '' |
bIncludeVideoFiles | If AllowUnknownFormats is false then video files are excluded by default. Set to true to include supported video file types such as AVI and MPEG. Thumbnails for video files will be retrieved from Windows Explorer if the format is specified in MViewExplorerThumbnailExts | False |
LoadOnDemand | If True (Default), images are only loaded as they are displayed (i.e. not until they are scrolled into view). Set to false to load all images immediately | True |
DefaultTopText | Specify the text that is applied to ImageTopText | iedtNone |
DefaultInfoText | Specify the text that is applied to ImageInfoText | iedtNone |
DefaultBottomText | Specify the text that is applied to ImageBottomText | iedtFilename |
bShowHiddenFiles | Enable to include hidden and system files | False |
bShowFolders | Enable to include folders | False |
FilenameFilter | Limits the file to filenames that contain text specified by FilenameFilter (see Filter for more detail) | '' |
Note:
◼Does NOT clear existing content. Use
Clear first to replace existing content
◼More functionality for the display of thumbnails of file folders is available with
TImageEnFolderMView◼If an invalid folder is specified an exception is raised
◼If you want to change text values after filling (e.g. with
DefaultBottomText), you should specify iedtNone for the Default*Text parameters

ImageEnMView1.Clear;
ImageEnMView1.FillFromDirectory( 'C:\Images\' );
// Which is the same as:
ImageEnMView1.FillFromDirectory( 'C:\Images\', iefAllImages );
// Get images and videos
ImageEnMView1.FillFromDirectory( 'C:\Images\', iefAllImagesAndVideos );
// Get all files
ImageEnMView1.FillFromDirectory( 'C:\Images\', iefAllFiles );
// Get only JPEG images
ImageEnMView1.FillFromDirectory( 'C:\Images\', iefCustom, '*.jpg;*.jpeg;' );
// To make it easier to change the text values, specify iedtNone at the time of filling
ImageEnMView1.FillFromDirectory( 'C:\Images\', iefAllImages, '', True, iedtNone, iedtNone, iedtNone );
ImageEnMView1.DefaultTopText := iedtFilename;
