I use InputChips in my app.
InputChip(
key: Key(label.id),
label: Text(label.name),
onDeleted: () => deleteChip(),
),
I want now to create unit tests to test the delete function. Unfortunatly I found no way to press the delete icon of the chip in the unit test. With await tester.tap(find.byKey(Key('1'))); it's possible to find the chip. How can I now define that I want to click the delete icon on the chip?
Your finder is finding and tapping the InputChip itself, not the "X" on the Chip.
Your finder should look something like:
find.descendant(
of: find.byKey(Key(label.id)),
matching: find.byIcon(Icons.cancel),
);
This says "find the descendent of the InputChip who is the cancel Icon. Then you can tap that if you'd like :)
When you're missing a tap-target, or aren't sure what is happening in the test, have a look at the console after running debugDumpApp();

So I'm making a button for a "New Note" in Swift UI similar to the Apple Notes app.
Right now my "New Button" is a "Navigation Link" like so:
NavigationLink(
destination: EditorView(makeNewNote())
) {
Text("New")
}
Unfortunately—this triggers my app to create a new note every time the view loaded. :(
:/
I've been looking for a way to initate a segue on button push but I'm not finding success on this yet.
When I tried a modal—I found myself having the same problem
Button("New") {
self.isNew = true
}.sheet(isPresented: $isNew, content: {
EditorView(makeNewNote())
})
I'm wondering what the best way to approach this would be.
Having no success :(
Edit:
I referred to this and the documentation but I haven’t found a way to segue via a button push which would be ideal. (The function dosent get triggered in the closure :)

Also...if you were curious what makeNewButton() does—it basically inserts a new Core Data object into my app’s managed context.
I'm not entirely sure, but it kinda sounds like to me your problem lies in your model. Because each time your View loads it calls the makeNewButton() function right?
Maybe you can fix the problem by displaying the "new note" view and having an extra "Save" button that only makes changes to your model once it's triggered.
Alternatively, you could use context.rollback() to discard changes. Also, check out this Project. It's Beta 4 but works just the same and imo is a good example how to use CoreData with SwiftUI. :)
I have to disable standard next button, on my custom page via installscript.qs file.
I can disable my own button (that I created in .ui file) via .qs script like this: widget.myButton.setEnabled(false);
This man shows that native buttons represented as enumeration and I cannot disable them same way.
Controller Scripting manual page shows some interactions with native buttons. Like gui.clickButton(buttons.NextButton). I go through whole gui object man and don't found anything useful.
Qt installer framework has a native license check page with Next button logic that I need, but I have not found any samples that do it manually. (license page work because its default license page and it's logic inside framework as I understand).
Finally I found isComplete() method that can be useful for me, but it is for C++ API not for qs.
So how to disable native button via installscript.qs file?
In case someone else end ups here, I finally found a cleaner solution: a dynamic widget has a property complete that can be changed to enable and disable the "Next" button. Set it to false to disable the button.
Controller.prototype.DynamicMyWidgetCallback = function()
{
var currentWidget = gui.currentPageWidget();
if (currentWidget != null)
{
currentWidget.complete = false
}
}
The only solution i had found is call installer.setValue("canContinue" "false");
Then connect page entered event using gui.pageById(QInstaller.TargetDirectory).entered.
connect(Component.prototype.targetPageEntered);
In targetPageEntered check our value:
Component.prototype.targetPageEntered = function () {
if (installer.value("canContinue") != "true") {
gui.clickButton(buttons.BackButton);
QMessageBox.information("someid", "Installer",
"You must do smth to continue", QMessageBox.Ok);
}
}
Of course you need to change the installer.value when user complete required actions.
How can I call a function on click of back button in Ionic 2 from a specific page?
I have the following scenario in my mind. Lets say I navigate like below:
PageA --> PageB --> PageC --> PageD
Now when I click back button on PageD I want to go back to PageB instead of PageC. I want to call below function on click of back button.
goBack(){
this.navCtrl.popTo(PageB);
}
I have done it Like this:
ionViewDidEnter(){
this.bindMethodToElement('back-button',this.goBack);
}
bindMethodToElement(elementClassName,functionToBind){
try{
let elements = document.getElementsByClassName(elementClassName);
let currentElement : Element = elements[elements.length - 1];
currentElement.addEventListener("click",functionToBind);
}catch(exception){
console.log(exception.message);
throw exception;
}
}
Does anyone know better approach to do it. I also want to achieve similar behavior when user clicks on the device back button.
Such a feature was already reported to the Ionic team and they are validating it. In the meantime you can use this workaround:
goBack(){
this.navCtrl.pop().then(() => {this.navCtrl.pop()});
}
Ugly solution but works. Good luck!
I'm new with Qt and I'm making a little application. I've do it with QWizard and QWizardPages.
I Have added 2 CustomButtons to the wizard so it has 5 buttons down: ButA, ButB, Back, Next/Finish, and Cancel.
ButA and ButB don't have to appear in all WizardPages. Eg:
WP0: just ButB
WP1: ButA and ButB
To do that, I have:
void WP0::initializePage()
{
wizard()->button(QWizard::CustomButton1)->setVisible(false);
}
With that when the app starts, you can't see butA. BUT if you go to the next page (where you see ButA and ButB) and then you click on BackButton, then you see ButA in WP0.
I supose that then you click on BackButton there is no call to WP0::initializePage() so my question is: how or where should I call that wizard()->button(QWizard::CustomButton1)->setVisible(false);
to never see ButA on WP0 ? Or what should I do?
I don't know if I understand your question completely. your description is kind of complicated. I think you should try button's events. It means you should call this function in press event or something like that and it's better that you define a boolean variable for true or false and call it by reference. I think this should solve your problem.
I have a button in one of view controller of tab bar controller. All set up in storyboard. I registered action method like this
- (IBAction)buttonPressed:(id)sender {
NSLog(#"Button pressed");
}
The thing is that once I make left and top constraints (to force it stay in the right upper corner) touch up inside event stops working after I change rotation. So just open app in portrait mode - method is working. Change to landscape and I cannot tap button suddenly.
I've recreated problem in this easy example project.
Many thanks.
Just put the following code in you TabBarViewController class.
- (void)viewDidLayoutSubviews
{
// fix for iOS7 bug in UITabBarController
self.selectedViewController.view.superview.frame = self.view.bounds;
}
Recently I noticed same bug in my application. First I tried Slavco Petkovski method. But this caused me another bug with rotating and getting right bounds and frame, so I kept searching.
I found another solution for this problem, mainly setting autoresizing mask of view controller's view in xib. But since arrows in inspector in my Xcode (version 5.0.1) are inactive and you can't set them, you have to open xib file in text editor find autoresizingMask property for main view and change it like this:
<autoresizingMask key="autoresizingMask" widthSizable="YES" heightSizable="YES"/>
EDIT:
Alternatively you can do this in your view controller's code - same result as in changes in xcode:
self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
