I was going to try out my new shiny xml resource based dialog with the
following code:
////JAVE
/// this is a test to see how to implement a dialog with patricks system
/// it replaces tMidiDelayDlg
void tPianoWin::ActMidiDelayDialog()
{
double scale = 0.5;
long clockDelay = 10;
int repeat = 6;
jppResourceDialog dialog(this, "midiDelay");
dialog.Attach("scale", &scale);
dialog.Attach("clockDelay", &clockDelay);
dialog.Attach("repeat", &repeat);
if(dialog.ShowModal() == wxID_OK) {
//execute the command
// tCmdMidiDelay cmd(Filter, scale,clockDelay,repeat);
// cmd.Execute();
Setup();//??
Canvas->SetScrollRanges();
Redraw();
}
}
////////////
It fails, because there are only long* prototypes of Attach.
Is this so by design or because floats havent been implemented?
I suspect it's by design, because I couldnt find a "double" capable
slider either.
I could of course use longs in the gui, and convert to double when
sending to the command object.
However, how would I show the user a float in the gui in that case?
BTW there are some other issues here. The old code is full of global
scope variables, which I find un-beautiful.
In this case "scale" and so on would be global. It was used so that the
dialog would remember state between invocations.
Do you still think this is the right way to do it?
Cheers,
/Joakim

I strongly suggest checking out the sliders in Audacity. They're real nice, have tooltips already to show the values stored, and are capable of displaying several different units of volume. They're both easy and hard to use, though. :( > I could of course use longs in the gui, and convert to double when > sending to the command object. > > However, how would I show the user a float in the gui in that case? > > BTW there are some other issues here.

All of these global variables are completely wrong. ;) I'm working on factoring them all out into jppProject, and you can take a crack at it already (I've added jppProject to the cvs now, even if it's not doing much yet). We need to collect all the global variables into jppProject (as much as it makes sense, anyway) and then write some solid interfaces to them within jppProject so we can then free the data from the implementation.

I implemented int* versions of the Attach methods. I also added
support for wxSlider. I didn't test any the recent changes, so it
may not work. I really need to head to bed.

Another possibility is adding Attach methods like this:
Attach(wxString name, double *ptr, double divisor);
When the values come out of the slider it automatically performs the
division for you. The sliders could be phrased in terms of percent
or something like that. The XRC resource controls the range and
labels on the slider.
Another possibility would be implementing our own double capable
sliders. Probably wouldn't be too hard, but not a trivial task
either.

Well, there are a couple of "double" capable controls in the jazz gui,
so we should figure out something to use at all such places.
What would be useful is a combination of string entry box and
a slider(or knob).
Is it difficult to create your own widget in wxwidgets?
or do I just subclass and instantiate 2 components within + glue logic,
and voila new component like in "Swing"(or whatever modern toolkit)?
How would the new component interface with wxwidgets gui builders like
xrced or wxDesigner?

It looks like you just somehow subclass wxWindow and go from there,
but I haven't tried it. That ASlider looks like a decent example.
There's a way to add "unknown" widgets in wxglade and xrced. wxglade
also provides a way to add properties, though I didn't figure out how
to access them. I'd figure out how to use it, but I have to run.
