Draw Methods doesn't work on GeUserArea

bentraje

Hi,

I'm trying to attach a simple GeUserArea with just a bunch of Draw Methods (i.e. DrawText etc) but it appears blank when I execute the script. There are also no errors on the console.

You can check the wip code here:

import c4d
from c4d import bitmaps, documents, gui, plugins, threading, utils

class UserArea(c4d.gui.GeUserArea):
    color = c4d.Vector(1, 0, 0)

    def DrawMsg(self, x1, y1, x2, y2, msg):
        self.DrawText("Test Text Area", 10, 10)
        self.DrawSetPen(self.color)
        self.DrawRectangle(x1, y1, x2, y2)

        return super(UserArea, self).Message(msg, result)
        return True


class MyDialog(c4d.gui.GeDialog):
    def CreateLayout(self):

        paramid = 10002

        self.AddUserArea(paramid, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 100, 100)
        self.AttachUserArea(UserArea(), paramid)

        return True

    def Command(self, id, msg):
        return True

    def CoreMessage(self, id, data):
        return True

if __name__ == "__main__":
    dlg = MyDialog()
    dlg.Open(dlgtype=c4d.DLG_TYPE_MODAL_RESIZEABLE)

Thank you for looking at my problem

The user area has to be a member variable of the GeDialog class:

class ExampleDialog(c4d.gui.GeDialog):
    # The GeUserArea need to be stored somewhere, we will need this instance to be attached to the current Layout
    geUserArea = ExampleGeUserArea()

See geuserarea_basic_r13.py.

Thanks for the response.
The DrawSetPen and DrawRectangle works but for some reason the
DrawGetTextWidth() doesn't.

I also used the value from the DrawGetTextWidth() but I still get the same result (i.e. the Text is not being drawn)

Here is the code so far:

import c4d
from c4d import bitmaps, documents, gui, plugins, threading, utils

class UserArea(c4d.gui.GeUserArea):
    color = c4d.Vector(1, 0, 0)

    def DrawMsg(self, x1, y1, x2, y2, msg):
        self.DrawText("Test Text Area", 67, 67)
        print self.DrawGetTextWidth("Test Text Area")
        #self.DrawSetPen(self.color)
        self.DrawRectangle(x1, y1, x2, y2)


class MyDialog(c4d.gui.GeDialog):
    
    ua = UserArea()
    def CreateLayout(self):

        paramid = 10002

        self.AddUserArea(paramid, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 200, 200)
        self.AttachUserArea(self.ua, paramid)

        return True

    def Command(self, id, msg):
        return True

    def CoreMessage(self, id, data):
        return True

if __name__ == "__main__":
    dlg = MyDialog()
    dlg.Open(dlgtype=c4d.DLG_TYPE_MODAL_RESIZEABLE)

Hi,

I haven't run your script, but you invoke DrawRectangle after DrawText, covering up any text you have drawn previously.

Thanks for pointing it out. It now works as expected.
