TAdvSmoothImageListBoxAdding items & extra properties in code
In this code sample, the image will be directly (non threaded) loaded in the TAdvSmoothImageListBox:
procedure TForm1.AddItems;
var
i: integer;
begin
//Adds 20 items
for i := 0 to 20 do
begin
with AdvSmoothListBox.Items.Add do
begin
Enabled := True;
//If enabled false then the item will be drawn in disabled fill
Visible := false;
//the item will be invisible
Image.LoadFromFile(‘image1.jpg’);
//the image will be loaded on the item
Caption.Text := ‘Item ’+ inttostr(i); Splitter := false;
//if splitter is true a splitter will be drawn between the items
…
end;
end;
end;To have the listbox background thread load the images for higher responsiveness of the application, following code can be used:
procedure TForm1.AddItems;
var i: integer;
begin
//Adds 20 items
for i := 0 to 20 do
begin
with AdvSmoothListBox.Items.Add do
begin
Enabled := True;
//If enabled false then the item will be drawn in disabled fill
Visible := false;
//the item will be invisible
Location := ‘image1.jpg’;
//the image will be loaded by thread
Caption.Text := ‘Item ’+ inttostr(i);
Splitter := false;
//if splitter is true a splitter will be drawn between the items
…
end;
end;
end;You can also add a whole directory of images either threaded or not threaded. When the threaded method is choosen, the images are loaded via a separate thread. This separate thread loads only the visible images for efficiency. As the list is scrolled, new visible item‟s images will be loaded by this thread.
Not threaded:
AdvSmoothImageListBox.AddImagesFromFolder(„C:\directory\*.jpg‟);
AdvSmoothImageListBox.AddImageLocationsFromFolder(„C:\directory\*.jpg‟);
Image types supported are: jpg, jpeg, bmp, png, gif, tiff and ico.
