I wonder why can't I see my blue buttons between the Images when running this code?
var body: some View {
NavigationView {
VStack {
ForEach(self.sets) { set in
NavigationLink(destination: DeferView { ExerciseVideoView(items: set.items).navigationBarBackButtonHidden(true) }) {
VStack {
Image("group-\(set.image)")
.resizable()
.renderingMode(.original)
.frame(height: 200, alignment: .leading)
.overlay(
Text(set.purpose)
.font(.largeTitle)
.fontWeight(.semibold)
.foregroundColor(.white)
)
Color.blue
.frame(maxWidth: .infinity)
.overlay(
Text(set.purpose)
.foregroundColor(.white)
)
}
}
}
}
}
I only see the images but Color.blue is hidden for some reason. Everything works fine without NavigationLink.
Is something wrong with rendering template?
Please advise

I'm unable to get ScrollTrigger working after a page transition.
I'm using the views data within the barbs.init.
/*PAGE TRANSITION*/
barba.init({
transitions: [{
name: 'opacity-transition',
leave(data) {
return gsap.to(data.current.container, {
duration: 0.5,
opacity: 0,
y: '50px',
});
},
enter(data) {
gsap.from(data.next.container, {
duration: 0.5,
opacity: 0,
x:'-50px',
});
}
}],
views: [{
namespace: 'tester',
beforeLeave(data) {
//alert('Leaving tester');
},
beforeEnter(data) {
//alert('Entering tester');
},
afterEnter(data) {
//alert('Entered tester');
ScrollTrigger.refresh();
}
}]
});
Most other code fires OK. However I cannot get gsap scroll trigger to work after a page transition. (Have the same issue with locomotive.js)
Can someone please advise what I might be doing wrong.
I'm new to Barba and ScrollTrigger, and have limited JS experience so an explicit answer would be very welcome.
You needed to add the ScrollTrigger.refresh(); to trigger when the animation ends, not the new page entered. You can do that using the onComplete property in your GSAP tween, as follow:
// ADD onComplete
enter(data) {
gsap.from(data.next.container, {
duration: 0.5,
opacity: 0,
x:'-50px',
onComplete: () =>{
ScrollTrigger.refresh(true)
}
And you can delete this in your Barba.js view
// DELETE THIS
afterEnter(data) {
//alert('Entered tester');
ScrollTrigger.refresh();
}
I have a TabView with 3 Tabs and I want to change the focus/select the third Tab when a button is pressed. I've tried forceActiveFocus, but it does not work.
//.qml
TabView {
Tab {
id: redTab
title: "Red"
Rectangle { color: "red" }
}
Tab {
id: blueTab
title: "Blue"
Rectangle { color: "blue" }
}
Tab {
id: greenTab
title: "Green"
Rectangle { color: "green" }
}
}
ToolButton {
inconSource: "lock.png"
onClicked: {
greenTab.forceActiveFocus() // does not work?
}
}
Set the currentIndex:
TabView {
id: tabView
//...
}
//...
tabView.currentIndex = 2
How I can change background color to red for row if row had timeToReply>15. I can't get timeToReply in rowDelegate. How I can do this ?
TableView
{
model: someModel
TableViewColumn{title:"Time";role: "timeToReply";width: 170}
rowDelegate: Item {
clip: true
Text {
anchors.verticalCenter: parent.verticalCenter
color: {
if(timeToReply>15) //problem
{
color="red"
}
else
{
color="black"
}
}
text: styleData.value
elide: Text.ElideMiddle
}
}
}
UPDATE
I wanna implement the setting by swiping the top bezel, here's my code am I doing this right? Currently this doesn't work. I wanna know how to implement it. Where should I put the code for it, and what do I lack of so that it'll work?

And here's the topsettings.qml
MenuDefinition {

onTriggered: {
cppObj.onSettingsClicked();
}
}
Settings is not displayed:
Your code looks good: the only issue is that you try to define your Menu.definition in a Page, but you should be defining it in a Pane. See here for example: https://github.com/Kernald/tt-rss-bb10/blob/master/assets/main.qml#L9
By the way, note that you have predefined actions for Help and Settings. See the link before, I used them too.
Let's say you have the NavigationPane as the QML document loaded first upon application launch, so that's should be placed in MenuDefinition like that:
NavigationPane {
Menu.definition: MenuDefinition {
helpAction: HelpActionItem {
onTriggered: {
}
}
actions: [
ActionItem {
title: "Action 1"
imageSource: "asset:///images/ic_action1.png"
onTriggered: {
}
},
ActionItem {
title: "Action 2"
imageSource: "asset:///images/ic_action2.png"
onTriggered: {
}
}
]
}
firstPage: Page {
}
}
Note, that there might be up to 4 elements and HelpActionItem as well SettingsActionItem are already defined if you want to implement similar menu entries.
I have a Container which is a DockLayout and in this Container is a other one as a StackLayout. And there I have a label which I want to center, but I can't get it to work.
I need some help.
Here is a small overview of the structure:
Container {
layout: DockLayout {
}
Container {
id: cAnzeige
Label {
id: lblHeader
textStyle.fontSize: FontSize.XLarge
text: "header"
}
verticalAlignment: VerticalAlignment.Top
layout: StackLayout {
}
}
}
1) Make the StackLayout fill the horizontal width:
horizontalAlignment = HorizontalAlignment.FILL
2) Make the Label centered:
horizontalAlignment = HorizontalAlignment.CENTER
StackLayout is excessive here. Using DockLayout in your case is enough:
Container {
layout: DockLayout {
}
Container {
id: cAnzeige
horizontalAlignment: HorizontalAlignment.Center
verticalAlignment: VerticalAlignment.Center
Label {
id: lblHeader
textStyle.fontSize: FontSize.XLarge
text: "header"
}
}
}
