The wxGBTool is short hand notation for wxWidgets Geometry Building Tool. wxWidgets is a cross-platform tool for developing graphical user interfaces which can be compiled on different platforms without having to make many modifications in the source code.
For GTK 2 running in a KDE environment, a screenshot for wxGBTool after it first starts up is given below. Note that on your system, the layout may vary, especially if you compiled wxGBTool for another toolkit than GTK 2. The functionality should remain the same, however.
In the black rectangle on the left, the scattering geometry is drawn. This window is not interactive and is only intended to visually discover geometry errors. You can not zoom or scroll in the window. Perfect conductors are drawn in red, dielectrics are depicted in green.
The file menu allows you to open and save *.gbt files, or to start a new geometry.
The panel of the right is divided into three sections:
A new geometry, excitation and output can be added to the scene by pressing the add button. A pop-up window will appear in which the correct settings can be chosen. The current geometries, excitations and output are listed in the corresponding comboboxes. The selected item can then be edited or deleted by pressing the corresponding button. We believe this is all straightforward.
A selected geometric item can also be duplicated to another location by
pressing the `duplicate' button. Enter a list of x ; y coordinates
where the objects should be copied to. An object can not be deleted without
first deleting the duplicated objects. When the object is edited, all of its
duplications are altered accordingly.
In the next section, we will discuss four sections in more detail.
