How to position a widget in the viewport and keep it responsive without a canvas panel?

[riukuh]

helo, i’m trying to create a context menu and an item inspector for my inventory, both should appear next to the slot and in both i’m not using a canvas panel. The way that i’m doing is: i’m getting the slot position and passing it to the HUD, which then passes it to these widgets to set their positions. However, it’s not working, and it’s not responsive: if I reduce the screen size, the widget moves extremely far away.

in full screen:

in widow mode:

here how i get my slot position in the slot widget:

FVector2D UInv_ItemSlot::GetSlotPosition() const
{
FGeometry Geometry = GetCachedGeometry();
FVector2D WidgetCenter = Geometry.GetLocalPositionAtCoordinates(FVector2D(0.5f, 0.5f));
FVector2D PixelPosition;
FVector2D ViewportPosition;
USlateBlueprintLibrary::LocalToViewport(GetWorld(), Geometry, WidgetCenter, PixelPosition, ViewportPosition);
UWidgetLayoutLibrary::GetViewportScale(this);
return PixelPosition;
}

and i get the slot position in my inspector and context menu and do this:

SetPositionInViewport(SlotPosition, false);

i already tested using false to bRemoveDPIScale, but nothing has changed

here my widget setup in editor:

i’m using a scale box to override the size, and it’s set to desire on screen with a value of 0.5 in pivot

Hello @riukuh ,
You could try adding the canvas panel and adjusting the anchors properly.

I am a learning beginner. What is the purpose of deleting the canvas when using multiple widgets? For example, some help guides will create a main HUD widget with say just health and magic progress bars. Then in another separate widget say for inventory they will delete the canvas and set the fill screen to desired. I sort of understand using the main HUD widget to call to get a reference to the Inventory widget. I don’t understand the significance not having a canvas on a widget. When I try t…

@riukuh

there’s a way to do it without a canvas?

i don’t think so. as it’s the canvas that provides some of those features.

you could implement your own logic for updating the layout, i think there’s a virtual function for that. but it sounds extremely convoluted. i don’t understand your restriction of not using a canvas.
