Hi Bernhard,
yes, the only demo for ltk is in fact the spinning lines demo. Demo's like the one you provide for your Celtk or Cells-TK would be really great for ltk. The reason why I use ltk is simply that I want to do it on my PowerBook and Cells and everything related to it seem only be supported on Linux and Windows. Or has anyone got it working on a Mac as well, either on openMCL or SBCL ?
I am also stuck again with my ltk trials. I know that e.g. "entry" delivers its content as text and this can be used with (text entry_variable) It seems to come from a tktextvariable, according to the source in ltk.lisp. I was able to display a slider (scale), but I have no idea on how to get its current value. What type is it ? Which method needs to be used to get it ? If only these informations were given in the ltk documentation, it would be really helpful. Unfortunately, the source seems to be the only documentation. Nice for Lisp geeks, but problematic for people like me ;-)
There is some Ltk documentation on the Ltk webpage (actually it even mentions the answer to your question...) but I have to agree that I could spend more time on it eventually. In general, all widgets where it is appropriate, either have the (settable) accessor "text" or "value", so for entries you can just read/set it with (text entry) assuming entry is your widget instance. All the widgets which inherit from tktextvariable have the text accessor, those who inherit from the tkvariable class have the value accessor. Peter
