I have a ListView that displays a checkbox, icon, and name of every png in a user-selected folder.
On the form is an Imagebox named "picPreview". I want to display an enlarged preview of the icon on the form when I hover over each item in the listview (the below code isn't valid code. It's simply what I'm seeking to do.)
Private Sub lsvCollection_MouseMove(sender As Object, e As MouseEventArgs) Handles lsvCollection.MouseMove
' Display enlarged preview of icon on Hover.
Dim currentItem As ListViewItem = lsvCollection.GetItemAt(e.X, e.Y)
For Each item As ListViewItem In lsvCollection.Items
If currentItem IsNot Nothing Then
BOGUS CODE> **picPreview.Image = lsvCollection.Items(currentItem.Index).Image**
End If
Next
End Sub
If I must, I can determine the image filename from the index and load it straight off the HDD, but that's slow & inefficient. Is there any way to obtain the currently focused icon from the ListView and simply re-display it?
TIA
ADDENDUM: I can obtain the image from the ImageList that was used to populate the ListView, but if the ListView is then sorted, the icons no longer match. :(
"Working" code: picPreview.Image = ImageList2.Images(currentItem.Index)
Handle the ListView.ItemMouseHover Event. The event will give you the listview item that the mouse is hovering over and you can use the imagindex from that item.
Thx for the reply.
I switched to "MouseHover" and changed "e.X, e.Y" to "MousePosition.X, MousePosition.Y)
But the line to read the image still doesn't work, so I need to figure out what to use instead.
I don't understand the need for a line when the suggestion that I posted allows for getting the image from an ImageList based on the listview item that the mouse is hovering over.
For example -
(Are you simply displaying the icon on the form? I'm trying to display the icon in a PictureBox control.)
You must have some code in your MouseHover event. The "line" of code in question needs to assign the ListView item's icon to the picPreview.Image.
There is a PictureBox on the Form.
Form method that does the magic -
Private Sub ListView1_ItemMouseHover(sender As Object, e As ListViewItemMouseHoverEventArgs) Handles ListView1.ItemMouseHover
PictureBox1.Image = ListView1.LargeImageList.Images.Item(e.Item.ImageIndex)
End Sub
(A small "oops". I was trying to use "MouseHover" instead of "ItemMouseHover", but there seems to be more to it.)
Hmm. I'm getting an error: Your line returns "Nothing".
FOLLOW UP: Works when I switched to "SmallImagesList". Big thx.
I just happened to use both Imagelists in the example.
If my answer solved your problem kindly accept it to close this issue.
I was looking for a way to mark a specific reply as the answer, not the first reply. :(
