SUMMARY

This article describes how to make an image browser.

DISCUSSION

As an example, we will create an application that has the user select a folder on his drive, and then populates a listbox object with all of the *.png and *.jpg files within that directory. The user clicks on a file in the listbox object, and clicks the "Open" button to load the selected image into the image object.

1. Create a project with two button objects, a listbox object, and an image object.
   
   
2. Label Button1 "Load" and Button2 "Open".
   
   
3. Insert the following code into the On Click event for Button1:

   --Disable listbox Updating
   
   
   ListBox.SetUpdate("ListBox1", false);
   
   
   --Get the desired folder to browse
   
   
   folder = Dialog.FolderBrowse("Open Folder", "C:\\");
   
   
   --populate tables with all the .jpg and .png files
   
   
   file_jpg = File.Find(folder, "*.jpg", false, false, nil);
   
   
   file_png = File.Find(folder, "*.png", false, false, nil);
   
   
   images = {file_jpg, file_png};
   
   
   --do the following for each file:
   
   
   for k in images do --loops through the different image types
   
   
         for j,file_path in images[k] do --loops through each image file
   
   
             --add the item to the listbox, with the name visible and path as data
   
   
             ListBox.AddItem("ListBox1", String.SplitPath(file_path).Filename, file_path);
   
   
         end
   
   
   end
   
   
   
   
   
   --Allow the listbox to display the updated content
   
   
   ListBox.SetUpdate("ListBox1", true);

4. Insert the following code into the On Click event for Button2:

   selected = ListBox.GetSelected("ListBox1");  
   
   
   for j,k in selected do
   
   
         Image.Load("Image1", ListBox.GetItemData("ListBox1", k));  
   
   
   end
