I am a new user of PV-Wave. Please forgive me to ask some stupid
questions about using of widgets.
I want to define a widget, first with the following command:
top = WwInit(title,'Examples',base,/form,/horizontal)
Actually, I also want to define the xsize and ysize of the widgets, but
I couldn't find any relevant information in references and programmer's
guide. Any pointer ??
In addition, I want to define a label for each new widget (e.g. slider,
text box, and radio box etc.) created. However, I found that it is very
inconvenient to do so as compared to IDL since in IDL, the definition of
label for each widget is very easy to define like
slider1 = Widget_Slider(base,TITLE='Slider 1',UVALUE='Slider',Min=1,Max=10)
for defining a slider. Furthermore, it is very inconvenient to define
procedure to handle all the events happened when we have a button pressed,
or pulldown menu selection, and it is not difficult to implement in IDL
by using CASE, though we still use CASE in PV-Wave's procedures.
Since I have written some programs in IDL and I need to change them into
PV-Wave, that's why I found the above problems and felt that PV-Wave is
not as good as IDL in implementation of widgets. For the above problems, any
help would be greatly appreciated. Thank you very much !
