The popup appears in the wrong place on first use

[L-Nafaryus]

Version of Dear PyGui

Version: 1.5.1
Operating System: Manjaro Linux (x86_64)

My Issue/Question

The popup appears in the corner of the primary window (pos [0, 0]) and expands (width = -1 argument for the child button) on first use.

To Reproduce

Steps to reproduce the behavior:

1. Right click on the tab.
2. See unexpected position and size.
3. Click somewhere to close popup.
4. Right click on the tab again.
5. See expected position and size.

Expected behavior

The popup should appear under the mouse position from the tab widget's hitbox with the correct size on every use.

            # First tab
            with dpg.tab(label = "tab1", tag = "tab1"):
                with dpg.popup(dpg.last_item(), mousebutton = dpg.mvMouseButton_Right):
                    dpg.add_button(label = "close", width = -1, callback = lambda: dpg.delete_item("tab1"))
                dpg.add_text("Tab!")
            # Second tab without width = -1 argument for the child button
            with dpg.tab(label = "tab2", tag = "tab2", show = True):
                with dpg.popup(dpg.last_item(), mousebutton = dpg.mvMouseButton_Right):
                    dpg.add_button(label = "close", callback = lambda: dpg.delete_item("tab2"))
                dpg.add_text("Tab 2!")

dpg.create_viewport(title = "New GUI", width = 1000, height = 800)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.set_primary_window("Primary", True)
dpg.start_dearpygui()
dpg.destroy_context()

I think it is because of popup window does not know where the pos of tab1 or tab2 is. If the frame is rendered one time. A correct popup position can be shown.

Check the dirty rendering code below for troubleshoot:

import dearpygui.dearpygui as dpg

dpg.create_context()

def call_me(s, a, u):
    print("call me")

with dpg.window(tag = "Primary") as primary:
    with dpg.child_window(tag = "Test", border = False):
        with dpg.tab_bar(label = "tabbar"):
            # First tab
            with dpg.tab(label = "tab1", tag = "tab1"):
                dpg.add_text("Tab!", tag="test")

dpg.create_viewport(title = "New GUI", width = 1000, height = 800)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.set_primary_window("Primary", True)

#dpg.start_dearpygui()

count = 1

while dpg.is_dearpygui_running():
    dpg.render_dearpygui_frame()

    if count == 1:
        with dpg.popup("tab1", mousebutton = dpg.mvMouseButton_Right):
            dpg.add_button(label = "close", width = -1, callback = call_me)

        count += 1

dpg.destroy_context()

I also found if you place the pop up code after set_primary_window, you can also get correct pop up pos for first time:

import dearpygui.dearpygui as dpg

dpg.create_context()

with dpg.window(tag = "Primary") as primary:
    with dpg.child_window(tag = "Test", border = False):
        with dpg.tab_bar(label = "tabbar"):
            # First tab
            with dpg.tab(label = "tab1", tag = "tab1"):
                dpg.add_text("Tab!")
            # Second tab without width = -1 argument for the child button
            with dpg.tab(label = "tab2", tag = "tab2", show = True):
                dpg.add_text("Tab 2!")

dpg.create_viewport(title = "New GUI", width = 1000, height = 800)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.set_primary_window("Primary", True)

with dpg.popup("tab1", mousebutton = dpg.mvMouseButton_Right):
    dpg.add_button(label = "close", width = -1, callback = lambda: dpg.delete_item("tab1"))

with dpg.popup("tab2", mousebutton = dpg.mvMouseButton_Right):
    dpg.add_button(label = "close", callback = lambda: dpg.delete_item("tab2"))

dpg.start_dearpygui()
dpg.destroy_context()

I'm also having this issue - using DPG 1.7.3. It seems to only happen to items+popups that were created before the app launches (i.e. created before dpg.start_dearpygui() is called).

Looks like it's something in set_primary_window that affects the popup position. Doesn't occur without set_primary_window; and, as @hugle mentioned, doesn't occur if popup is created after set_primary_window (but still before start_dearpygui).

[v-ein]

Look ma!

static PyObject*
set_primary_window(PyObject* self, PyObject* args, PyObject* kwargs)
{

<...>

	// reset other windows
	for (auto& window : GContext->itemRegistry->windowRoots)
	{
		if (window->uuid != item)
		{
			<...>

			window->info.dirtyPos = true;
		}
	}

set_primary_window certainly needs a bit of a redesign. Setting the "dirty pos" flag on a popup is exactly what makes that popup picking up the (0, 0) position on its first appearance (see #1975 and the corresponding fix).
