Hello, I implemented a HMI (Human Machine Interface) for the MatPLC project http://mat.sf.net (an OSS project) that uses Glade as its graphical builder. It is actually the official HMI editor for this project. There is a type of HMI where one draws a representation of the machine and then places widgets to view or control parts of the machine. There is a library of standard parts of a machine like pipes, valves, etc. Using the "Fixed Positions" type of layout one should be able to draw the machine from the library images, the problem is that there is no way of scaling the images. How difficult would it be to add a scaled toggle to the Properties dialog of the GtkImage and to have the image scaled to the whole widget size. When the widget gets rescaled the image will reflect this.
Maybe this screenshots of an application built using glade and executed using hmi_gtk and MatPLC can help visualize what is this all about. http://www.ace-lab.com/jorozco/ We are upgrading the HMI_GTK module to glade2. In the glade1 version we used GnomePixmap to do this. It did not scale to the widget size but instead used two parameters "scaled width" and "scaled height". This is not very practical but it worked, also this is deprecated widget and when we use libglade-convert this widget gets converted to a GtkImage. So we would prefer to use GtkImage if only we could scale the images and see a feedback of it. BTW, I am also interested in custom widgets with visual feedback, this is that one can see the custom widget in the design window in its real form. I am thinking something similar to the way a graphical java bean is represented in a IDE tool. Is something like this planned in the new Glade3 development? Bonobo components perhaps? I know there is a custom widget in Glade2 but it gets drawed as a plain square. I am pushing my luck here, but it would be great if this custom widgets could be placed in a palette.
