Objects created in real time

Kantronin

Hi,
I an converting all my C.O.F.F.E.E scripts to python.
But I have a problem with python at the real-time display of the objects I create.
I synthesized this problem in the simplified script below.
If I press on the button <Creation null polygon> the polygon will only show on the screen when I close the plugin window.
How to make the polygon appear on the screen without being obliged to close the plugin window ?

import c4d
from c4d import gui, documents

button_1 = 1000

class MyDialog(c4d.gui.GeDialog):
	def CreateLayout(self):
		self.SetTitle("Creation polygon")	
		self.AddButton(button_1, c4d.BFH_LEFT, 300, 24, "Creation null polygon")
		self.GroupEnd()
		
		return True

	def Command(self, cid, msg):
		if cid == button_1:
			polygon = c4d.BaseObject(c4d.Opolygon)
			doc = c4d.documents.GetActiveDocument()
			doc.InsertObject(polygon)  
			c4d.EventAdd()

		return True

class MyCommandData(c4d.plugins.CommandData):
	def Execute(self, doc):
		dlg = MyDialog()
		dlg.Open(c4d.DLG_TYPE_MODAL, -1, -1, 400, 200)
		dlg.InitValues(self)
		return True

if __name__ == "__main__":
	c4d.plugins.RegisterCommandPlugin(id=10000015, 
                                      str="Creation polygon", 
                                      info=0, 
                                      icon=c4d.bitmaps.BaseBitmap(), 
                                      help="", 
                                      dat=MyCommandData())

Hi,

have you tried using a non-modal dialog? I am using dialogs not very often, but it could be possible that the modal dialog blocks redraws of your scene.

dlg.Open(c4d.DLG_TYPE_ASYNC, -1, -1, 400, 200)

Sometimes you have also to invoke a redraw manually.

c4d.EventAdd(c4d.EVENT_FORCEREDRAW) 

or

c4d.DrawViews(c4d.DRAWFLAGS_NONE)

Cannot say much else, do not have c4d here to test your code.

You are calling the Dialog via DLG_TYPE_MODAL. So the Dialog is blocking the main thread until you close it.
Try opening the dialog with DLG_TYPE_ASYNC.

It was indeed the modal window that prevented the real-time display of objects.
By putting the code below, the display of objects is immediate.

class MyCommandData(c4d.plugins.CommandData):
def Execute(self, doc):
self.dlg = MyDialog()
self.dlg.Open(c4d.DLG_TYPE_ASYNC, -1, -1, 400, 200)
return True

However, the plugin window opens to the left of my screen and to move it to the center of the screen, I must first enlarge it.
I find that a little strange !

But it can be considered that my problem is solved.

Thank you for your answers

@Kantronin said in Objects created in real time:

  self.dlg.Open(c4d.DLG_TYPE_ASYNC, -1, -1, 400, 200)
However, the plugin window opens to the left of my screen and to move it to the center of the screen, I must first enlarge it.

The GeDialog manual says:

If xpos=-1 and ypos=-1 the dialog will be opened at the current mouse position.
If xpos=-2 and ypos=-2 the dialog will be opened at the center of the screen.

So, if the dialog opens to the left of your screen, I guess that's where your mouse was? Try -2, -2.
