Generated Editors
Detailed hints for installation and usage
Installation
The generated editors can be installed on Linux or Solaris systems.
For installation, the C++ compiler g++ and Tcl/Tk 8 is required.
After unpacking the archive, following comands have to be executed in the source directory:
The editor can be started by the command "make run".
In some cases, there is a segmentation fault when the editor is started.
It has something to do with optimizations for gcc. Add the following option
to the list of CFLAGS: -U__GNUC__
Usage
Although the editors are quiet user-friendly, you should pay attention to following hints:
- New language elements can be created using the toolbar on the left hand side of each window.
This is done by dragging a button and dropping it at the desired position.
So, the left mouse button has to be pressed during this operation!
The nearest matching insertion point will be highlighted by the editor. If there are
multiple nearest insertion points, the active insertion point will be rotated periodically.
- All visual objects habe a context menu. It can be used to open a dialog window to change some
attribute values or to open substructure-views.
- In some editors, line connections are created like "ordinary" visual objects.
In this case, a line connection has to be constructed by two steps: First, the
line has to be dragged to a arbitrary position inside the window.
After that the endpoints of the line can be connected to the target objects.
In other editors, lines can be created in one step by dragging one object to another.
Valid startpoints for this operation are shown by an special mouse cursor.
