Can `set_primary_window` use `horizontal_scrollbar` feature normally?

[tattataattt2]

Just copy can paste code below can reproduce the issue. horizontal_scrollbar=True but horizontal_scrollbar cannot show in screenshot below.

*Horizontal_scrollbar do not show normally

I got the same issue, but I think I found a workaround. It works if you configure the item after setting it as the primary window :

with dpg.window(tag="Main Window"):
    dpg.add_image("texture_tag", tag="image1")


dpg.set_primary_window("Main Window", True)
dpg.configure_item("Main Window", horizontal_scrollbar=True)

Thanks for your help!!! It works!!!

The root cause is that set_primary_window overrides window->configData.windowflags entirely, instead of fixing just those of them that are needed for the primary window. Until this is fixed, @Tetane's workaround is the way to go.

Another side effect of set_primary_window is that it can modify other windows, in particulary, by marking the window position as dirty. This affects positioning of modal windows:

• By default, a modal window is centered by DPG;
• If a modal window is created with show=False (with the intent of being displayed later), and set_primary_window is called on another window, the modal window will be displayed in top left corner instead of being centered. This is because it gets dirtyPos=true during set_primary_window.
