(Posted 21 years ago)
Commands are similar to Blitz+'s. GUI is compatible with Blitz3D and BlitzPlus. You can download the source code with an example from here.

CreateGuiCloseButton() will add a close button (top-right corner) to a window.
Listbox doesn't have a scrollbar.

It includes the following functions:
Refresh()
Runtime(MouseX, MouseY, MouseXSpeed, MouseYSpeed, MouseHit)

CreateGuiWindow(title$, x, y, width, height)
CreateGuiButton(text$, x, y, width, height, parent)
CreateGuiCloseButton(parent)
CreateGuiLabel(text$, x, y, width, height, parent)
CreateGuiCheckbox(text$, x, y, width, height, parent)
CreateGuiRadioButton(text$, x, y, width, height, parent, Group)
CreateGuiPanel(text$, x, y, width, height, parent)
CreateGuiSlider(x, y, width, height, parent)
CreateGuiTextField(text$, x, y, width, height, parent[, flag]) - flag 1 = password
CreateGuiTextArea(text$, x, y, width, height, parent)
CreateGuiImage(image, x, y, parent[, frame])
CreateGuiListbox(x, y, width, height, parent)
