Dynamically add and remove controls

[Dicko]

I use Eto in Rhinoceros in Python.

In this example the user should be able to add a new control by clicking a button.

I am able to add a control after initialization of the dialog (line 47), but when I click a button to add a control, it does not show (line 43).

As far as I can debug, I do create a new group and row, but adding it to the layout doesn’t work…

Here’s my basic code:

import Eto.Drawing as drawing
import Eto.Forms as forms


class Group(forms.GroupBox):


    def __init__(self, count):
        self.Padding = drawing.Padding(5)


        buttonRemoveGroup = forms.Button(Text = 'Remove this group')
        buttonRemoveGroup.Click += self.ButtonRemoveGroupClick


        self.Content = buttonRemoveGroup


    def ButtonRemoveGroupClick(self, sender, e):
        self.Detach()


class MyDialog(forms.Dialog):


    def __init__(self):
        self.Title = 'Add and delete controls'
        self.ClientSize = drawing.Size(300, 500)
        self.Padding = drawing.Padding(10)
        self.Resizable = False


        self.countGroups = 0


        self.buttonAddGroup = forms.Button(Text = 'Add group')
        self.buttonAddGroup.Click += self.ButtonAddGroupClick


        self.layout = forms.DynamicLayout()
        self.layout.AddRow(self.buttonAddGroup)
        self.layout.AddRow(None)


        self.Content = self.layout


    def AddGroup(self):
        self.countGroups += 1
        group = Group(self.countGroups)
        self.layout.AddRow(group)
        self.layout.AddRow(None)


    def ButtonAddGroupClick(self, sender, e):
        self.AddGroup()


def TestMyDialog():
    dialog = MyDialog()
    dialog.AddGroup()
    dialog.ShowModal()


if __name__ == '__main__':
    TestMyDialog()

I think you may have better luck asking on McNeel's discourse channel. Go to discourse.mcneel.com

Thanks Will.

I already did, so I thought this is the last possibility :)

The solution: Create()

def AddGroup(self, msg):

    self.countGroups += 1
    group = Group(self.countGroups)
    self.layout.AddRow(group)
    self.layout.AddRow(None)

    self.layout.Create()
