Listview Icons

[muXed]

Afternoon all.

After a few really good examples of the listview I seem to have cracked it and managed to design a program based all around it for a client.

However I read on microsoft that listviews can contain icons. Is this something that can be achieved with liberty?

Thanks in advance

This is a feature that I hope to include in Liberty BASIC 5.

I cannot really think of a reason why one would not be able to do this using the Window's ListView control.

You mean with API calls?  I do not plan to add any new features to the v4.x line of Liberty BASIC.

Yep in 4.x listview is API. I have a recollection that images can be included in the API build of the control. But we are well outside 4.x native capability.


Many folks will need to get used to living without API in 5.x

Yes, I meant "Window's ListView control" in LB4.x.

The OP will need to create an Image List and then send that to the ListView Control.

To do this, you will want to check out the List-View Image Lists page.

Unfortunately, there's quite a long ways to go before some people could port their working programs over to V5 since a lot of the advanced features are developed by using the Windows API.

Don't get me wrong, I am looking forward to the day that can happen, but I also see that it might still be a long way away.

Here are a couple of functions that will help you along. It will definitely help out if you search around for the ListView examples that I have thrown out there since the programming style will obviously be the same.

   Function createImageList(sizeX, sizeY, flags, numImages, canGrowBy)
       CallDLL #comctl32, "ImageList_Create", sizeX            As long, _
                                              sizeY            As long, _
                                              flags            As ulong, _
                                              numImages        As long, _
                                              canGrowBy        As long, _
                                              createImageList  As ulong
   End Function

   Function addImageToImageList(hImageList, hBitmap, hBitmapMask)
       CallDLL #comctl32, "ImageList_Add", hImageList          As ulong, _
                                           hBitmap             As ulong, _
                                           hBitmapMask         As ulong, _
                                           addImageToImageList As long
   End Function

You will need to send the LVM_SETIMAGELIST message to the ListView, along with the appropriate information, after you create the control.

Here is another tip.  You will most likely want to use the LVSIL_SMALL constant.  The value of LVSIL_SMALL is 1; it is not a constant that is included within Liberty BASIC so you will have to either use a hard coded one or make a variable for it.

I hope that will help you get started with what you hope to accomplish.

Many thanks all for the help.

Will give it a crack
