Graphics / VB.NET Transparent RenderWindow
« on: May 24, 2015, 12:20:16 am »
I have no idea if what I am trying to do is even possible because I am just starting out using SFML with VB.NET.
I currently have a picturebox that displays an image. I am trying to use a control, a panel in this instance with transparent backcolor, to display on top of the picturebox, with about 50% transparency so the picturebox's image shows through the panel. The panel will have additional controls inside of it that I would like to make transparent as well, but for now I am just trying to turn the panel slightly transparent.
Here is my code so far:
This shows the backcolor of the parent form both controls are on...so that obviously is not it. I have done some searches on the forum here, but there is not a lot of VB.NET that I have found, and I am probably searching for the wrong terminology. I'm probably doing this wrong anyways.
I would appreciate a point in the right direction or a better idea of how to display a half-transparent control over an image. Thanks.

Public ItemWindow As RenderWindow

ItemWindow = New RenderWindow(frmMain.pnlItem.Handle)
End Sub
Sub DrawInventory()
ItemWindow.Clear(ToSFMLColor(frmMain.pnlItem.BackColor))
' add items here
ItemWindow.Display()
End Sub
Public Function ToSFMLColor(ToConvert As System.Drawing.Color) As SFML.Graphics.Color
Return New SFML.Graphics.Color(ToConvert.R, ToConvert.G, ToConvert.G, ToConvert.A)
End Function
Sub InitGraphics()
ItemWindow = New RenderWindow(frmMain.pnlItem.Handle)

ItemWindow.Clear(ToSFMLColor(frmMain.pnlItem.BackColor))
