Is there any equivalent of the Spacer() element from SwiftUI?

[alexmocanu]

Hello,

Is there anything similar to the Spacer() control from SwiftUI in Adwaita-swift?

In SwiftUI I would write something like this:

HStack {
    Text("Left Text")                    
    Spacer()
    Text("Right Text")    
}

The first text would be pushed to the left and the second to the right.

What is the Adwaita equivalent, or is there an alternative to this?
Sorry if my question seems basic. I'm familiar with SwiftUI, but I'm still trying to find my way around Adwaita.

Here is an example of what I'm trying to do:

ListBox(self.items, content: {element in 
	HStack {
		Text(element.title).halign(.start)
		Text(element.numItems).halign(.end)
	}.padding()
})

The first text should be aligned to the left and the second to the right, both on the same line. But they're both aligned to the left:

If I remove the HStack, the alignment works, but each text will be displayed on a separate line.

What I'm looking to do is something like this:

In the end, after taking a look at the upstream documentation for Adwaita, I improvised something using the xalign and frame methods:

HStack {
	Text(element.title).xalign(0).frame(minWidth: 130).padding()
	Text(element.numItems).xalign(2).padding()
}

Have you tried:

HStack {
    Text("Left Text")
        .hexpand()
        .halign(.start)
    Text("Right Text")
}

halign makes the widget align inside the widget's frame (the one of Text itself, not of HStack). Therefore, you need to make the widget's frame expand via hexpand. The frame of the parent (HStack) will automatically expand as well.

You have to set halign to start to make sure the widget aligns correctly inside the expanded frame.

Because the width of Text("Right Text) is the width of the text itself (no expanding), setting halign(.end) is not necessary.

Exactly the same result could be accomplished by expanding the right text:

HStack {
    Text("Left Text")
    Text("Right Text")
        .hexpand()
        .halign(.end)
}

Thank You,

Your suggestions worked and are a lot better than my improvisations.
I went with the second one (expanding the text on the right).
