Scripting bug in QML ?

VeNToR

Hi;

By the following, when I click the button, first time is OK. But second click closes all the windows with out any exception, error etc...

Any one can try it on own codes ?

....
onClicked:
{
function CChRSMFile()
{
}

CChRSMFile.prototype.ChPut = function(
	ChData)
{
	print("It's OK...");
}

var ChBuffer = "";

for (var i = 0; i < 8192; i++)
	ChBuffer += ".";

for (var i = 0; i < 50; i++)
	ChRSMFile.ChPut(
		ChBuffer );

}
...

Hi,

You should post a complete example if you want people to be able to reproduce your situation.

You should also add the Qt version you are using as well as platform you are running on.

@SGaist Yes, you are right ! I am trying to minimize and localize the problem to understand by others... But at this point I can say this is very interresting problem...

Simplized codes are following;

main code;

import QtQuick 2.9
import QtQuick.Controls 2.3
import QtQuick.Controls.Material 2.1
import QtQuick.Layouts 1.3

import Qt.labs.settings 1.0

import Content 1.0

ApplicationWindow
{
id : window
width : 1024
height : 768
visible : true
title : "Quasar"

SwipeView
{
	id	: chSwipeView

	anchors
	{
		fill	: parent
	}

	Component
	{
		id	: chComponent

		Loader
		{
			asynchronous	: true			
		}
	}

	Timer
	{
		interval	: 500
		running		: true
		repeat		: false

		onTriggered	:
			{
				var	ChItem;

				ChItem = chComponent.createObject();

				if (
					chComponent.status == Loader.Ready)
				{
					ChItem.source = "Content/ChPageTest.ui.qml";

					chSwipeView.addItem(
						ChItem);

					chSwipeView.currentIndex = chSwipeView.count - 1;
				}
			}
	}
}

}

Content/ChPageTest.ui.qml code;

import QtQuick 2.9
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.3

Item
{
anchors.fill : parent

Button
{
	text:"test me"

	onClicked:
	{
		var ChRSMFile;

		function CChRSMFile()
		{
		}

		CChRSMFile.prototype.ChPut = function(
			ChData)
		{
			print("test");
		}

		ChRSMFile = new CChRSMFile();

		var s = "";

		for (var i = 0; i < 65535; i++) s+="a";

		for (var i = 0; i < 50; i++)
			ChRSMFile.ChPut(
				s);
	}
}

}

I solved, do not forget to give parent item to createObject.
