Create chamfered rectangles

I want to draw a chamfered rectangle, I define the drawing area, use the corresponding method, it doesn’t seem to work

import Eto.Forms as ef
import Eto.Drawing as ed
 
form = ef.Form()

drawable = ef.Drawable()
drawable.Width = 300
drawable.Height = 300

def draw(sender, e):
    rect = ed.RectangleF(10, 80, 140, 80)
    ed.GraphicsPath.GetRoundRect(rect,10) #Test

drawable.Paint += draw

stack_layout = ef.StackLayout()
stack_layout.Spacing = 8
stack_layout.Padding = ed.Padding(8)

bu = ef.Button()
bu.Text = "test"

stack_layout.Items.Add(ef.StackLayoutItem(drawable))
stack_layout.Items.Add(ef.StackLayoutItem(bu))

form.Content = stack_layout

form.Show()

Hi @tom33,

Is this what you are after?

The issue in your code is that GetRoundRect only creates the path it doesn’t draw it on the screen, you need to a make a separate call to DrawPath or FillPath for it to actually show up.

#! python3
import Eto.Forms as ef
import Eto.Drawing as ed


bg_debug = ed.Color.FromArgb(0,0,150,50)
b_debug = ed.Color.FromArgb(0,0,150,255)

form = ef.Form()

drawable = ef.Drawable()
drawable.Padding = ed.Padding(5)
drawable.Width = 300
drawable.Height = 300

# Rectangle
rectPen = ed.Pen(b_debug, 6)
strokeWidth = 14


def draw(sender, e):
    try:
        rect = ed.RectangleF(drawable.Padding.Left, drawable.Padding.Top, 140, 80)
        rounded_rect_path = ed.GraphicsPath.GetRoundRect(rect, strokeWidth)  # Test
        e.Graphics.FillPath(bg_debug, rounded_rect_path)
        e.Graphics.DrawPath(rectPen, rounded_rect_path)


    except Exception as ex:
        print(f"draw exception: {ex}")

drawable.Paint += draw

stack_layout = ef.StackLayout()
stack_layout.BackgroundColor = bg_debug
stack_layout.Spacing = 8
stack_layout.Padding = ed.Padding(8)

bu = ef.Button()
bu.Text = "test"

stack_layout.Items.Add(ef.StackLayoutItem(drawable))
stack_layout.Items.Add(ef.StackLayoutItem(bu))

form.Content = stack_layout

form.Show()

Sir, I have a question for you. def draw(sender, e), I have a question here. Is the “e” in the function argument “Eto.Drawing”?
So “sender” what is this? I don’t seem to understand this
