Image viewer ============ This example application shows how to load and show image/graphical files. It also demonstrates - scaling images - using the Lazarus functions FindFirstUTF8 and FindNextUTF8 to recursively seek files and directories - dealing with key presses using the KeyDown event - using BeginUpdate and EndUpdate to improve processing speed of certain controls (a ListBox in this case) - setting the cursor to hourglass and reset it to indicate a long-running operation is going on (e.g. when recursively loading directories with a large amount of images) Possible improvements: = add support for other file formats (e.g. tiff) - add a setting that allows automatic scaling down if a picture is larger than the control - use a cache in a different thread to preload images the user is likely to look at next
