Hi,

I looked at the Python SDK and could not find a detailed explanation, so let me ask two questions about DrawCustomButton().

1. What is the 5th argument "ids" for?

2. Is there a way to receive a message or something when I click on the button?

Here is a simple script that opens a dialog with a UserArea and draws a button.
It looks like just a rectangle is drawn, but I wish I could create an interactive button that can receive triggers with InputEvent() or Message().

Thank you!

import c4d

class MyUserArea(c4d.gui.GeUserArea):
    def DrawMsg(self, x1, y1, x2, y2, msg_ref):
        # Initializes draw region
        self.OffScreenOn()
        self.SetClippingRegion(x1, y1, x2, y2)
        self.DrawRectangle(x1, y1, x2, y2)
        # Draws black background
        self.DrawSetPen(color=c4d.Vector(0))
        self.DrawRectangle(x1, y1, x2, y2)
        # Draws a button
        self.DrawCustomButton(x=20, y=20, w=80, h=40, ids=[0], nofill=False, focus=False)


class MyDialog(c4d.gui.GeDialog):
    ua = MyUserArea()
    def CreateLayout(self):
        area = self.AddUserArea(id=0, flags=c4d.BFH_SCALEFIT|c4d.BFV_SCALEFIT)
        self.AttachUserArea(ua=self.ua, id=area)
        return True

def main():
    dialog = MyDialog()
    dialog.Open(dlgtype=c4d.DLG_TYPE_MODAL, defaulth=200, defaultw=200)

if __name__ == '__main__':
    main()

Great, thank you!

Hi,
There seems to be a problem with DrawEllipseFill() and DrawEllipseLine().

Here is a simple script that opens a dialog that draws two different circles in the UserArea.
Both circles are supposed to be a circle with 10px radius at different positions, but the second argument "radius" does not seem to work.

Please let me know if I am doing it wrong or if there is another way to draw a circle in UserArea. Thanks!

import c4d

class MyUserArea(c4d.gui.GeUserArea):
    def DrawMsg(self, x1, y1, x2, y2, msg_ref):
        # Initializes draw region
        self.OffScreenOn()
        self.SetClippingRegion(x1, y1, x2, y2)
        self.DrawRectangle(x1, y1, x2, y2)
        # Draws Circles
        self.DrawSetPen(color=c4d.Vector(1,1,1)) # White
        self.DrawEllipseFill(centerPoint=[100, 50], radius=10) # Filled Circle
        self.DrawSetPen(color=c4d.Vector(1,0,0)) # Red
        self.DrawEllipseLine(centerPoint=[50, 100], radius=10) # Line Circle


class MyDialog(c4d.gui.GeDialog):
    ua = MyUserArea()
    def CreateLayout(self):
        area = self.AddUserArea(id=0, flags=c4d.BFH_SCALEFIT|c4d.BFV_SCALEFIT)
        self.AttachUserArea(ua=self.ua, id=area)
        return True

def main():
    dialog = MyDialog()
    dialog.Open(dlgtype=c4d.DLG_TYPE_MODAL, defaulth=400, defaultw=400)

if __name__ == '__main__':
    main()

Result:

Hi,

I would like to get the Ease data copied by the "Copy Ease" function in the timeline, modify the data, and then paste it into another curve.

Is there a way to do that? Thank you.

Hi,

It looks like the problem got solved by Sized function.
Thanks a lot @m_magalhaes and @m_adam !!

@m_magalhaes
The versions I have checked are R21.207 and S24.037 on Windows.
I also checked with S24 on Mac and there was no problem.

The problem shows up when it is docked next to the timeline, especially in the lower left corner of the animation layout like this.

Hi,

I am trying to use UserArea to draw a simple 4x4 grid in a dialog, and docking it with the Timeline.
The issue is when I click around the UserArea and the Timeline(which is built-in UserArea??), top and bottom edges of the UserArea behave strangely.
And when I tweak the size of the dialog to redraw the UserArea, it returns to normal.

The same issue can be seen with the official plugin sample Py-MemoryViewer.
In this one, Redraw() is called frequently, so it returns to normal display immediately.

I know that this issue is not that critical, but is there any solution? Thank you.

Sorry, I forgot to mention that I'm developing in Python.
Thanks to your help, I seem to be able to display DescriptionCustomGui in my dialog only if I set an object to display via SetObject(), but this time I'm not seeking to display description of existing objects.
I'm still confused how to load .res file in description folder and display gadgets in my dialog.
Or is that impossible with .pyp ?

Hi,

I found that some of dialogs contain desc datas unlike others, for example Soft Selection Manager and Weight Manager. Also, those dialog's .res files are located in description folder, not dialogs folder.

And I tried to make a command plugin that open a dialog including desc datas via .res file in description folder, but I'm not sure how it works.

Does anyone know the way to build a dialog with those resources (especially Spline GUI) ?
I hope I'm not asking stupid question.
Thank you!
