Jmix 2.2.3
I need to change a View page title during runtime.
The end result should be like this Change title of the view at runtime
But this doesn’t work for me because it happens too early, I need to do it after the data components are initialized, so that I can construct the page title from the data.
Kind regards,
Mladen

fun setPageTitle(title: String) {
when (val window = getParentWindow(this)) {
is StandardMainView -> {
findComponent(window, "viewTitle").getOrNull()
?.let { it as? HasText }
?.let { it.text = title }
}
is Dialog -> {
window.headerTitle = title
}
}
}
fun getParentWindow(component: Component): Component? {
return when (val parent = component.parent.getOrNull()) {
is StandardMainView -> parent
is Dialog -> parent
else -> parent?.let { getParentWindow(it) }
}
}
Thank you Yaroslav, this is very nice Kotlin help.
I was able to use this to do it with Java.
I found out that to change the page title, as in the title on the browser tab (Chrome) one can do this:
getUI().ifPresent(ui -> ui.getPage().setTitle(pageTitle));
and to change the View title
getUI().ifPresent(ui -> ui.getPage().executeJs("document.getElementById('viewTitle').textContent = $0", pageTitle));
From your example we can also learn that it is not the same if the View is a dialog or not, so we need to test that if we are to change it in general.
Kind regards,
