Labels are arbitrary strings that anyone can add.

I don't know what OTE is. I'll guess "Over The Ether" (compare to OTA - Over 
The Air).

Re: [Interest] Qml Tooltips

[Jérôme Godbout]

For people who may get interested into making tootips too without accessing
the Qml private API:

Here's what I end up doing (a simplified version of one that does load the
item into a Loader container), I can now display any Items no more Z
fighting, have a single timer.

Hope this help some peoples ;-)

// ToolTipArea.qml (I place those inside the Item I want to make a tooltips
for
MouseArea
{
id: component
property string text
property Item content: Text { parent = null; text: component.text; }
property int interval: 750
anchors.fill: parent
hoverEnabled: true
propagateComposedEvents: true
preventStealing: true
acceptedButtons: Qt.NoButton
onExited: hide()
onCanceled: hide()
function hide()
{
if(ToolTipTimer.content == component.content)
ToolTipTimer.hide();
}
function show()
{
if(ToolTipTimer.content != component.content)
{
ToolTipTimer.interval = component.interval;
ToolTipTimer.content = component.content;
}
else
ToolTipTimer.start();
}
onContainsMouseChanged:
{
if(containsMouse)
show();
else
hide();
}
onPositionChanged:
{
hide();
if(containsMouse)
show();
}
}

// Make this ToolTipTimer as singleton into qmldir, use a single timer for
all tooltips
pragma Singleton
import QtQuick 2.3
import QtQuick.Controls 1.2

MouseArea
{
id: component

parent: Application.rootItem // Expose the root Item for the QQuickView
into c++ Application singleton anchors.fill: parent
visible: false z: 100
acceptedButtons: Qt.AllButtons

property Item content
property alias interval: timer_.interval
property alias running: timer_.running
onContentChanged:
{
if(content == null)
hide();
else
start();
}

onPressed : { hide(); mouse.accepted = false; }

function hide()
{
timer_.stop();
visible = false;
if(content) content.parent = null;
content = null;
}
function start()
{
timer_.restart();
}
function display()
{
if(!content) return;
content.parent = component;
var pos = Application.cursorPosition(); // Expose Q_INVOKABLE into
Application singleton that do the following: return qquick_view->
mapFromGlobal(QCursor::pos()); content.x = pos.x; content.y = pos.y;
visible = true;
}
Timer
{
id: timer_
running: component.content
interval: 750
onTriggered: component.display()
}
}

[Interest] QML/C++ tidbit

[m...@rpzdesign.com]

Hello List:

For those who are using Loader in QML but triggering that loader from 
C++, I came across a usage pattern technique that may have utility for some.

During the execution of the C++,  loading "componentSource" is NOT a 
synchronous operation if your loader is set to Async == true

In the Loader::onLoaded() function, call an INVOKABLE back into C++ to 
inform C++ that the loader is finished by setting some visible C++ flag

Then inside your C++, execute QGuiApplication::processEvents() 
immediately after setting "componentSource" and wait for the flag to be 
set and then you may proceed to interact with the freshly loaded QML 
objects inside C++ knowing the loader has finished its job.

This allows what is largely an asynchronous process to be made more 
"synchronous" inside your C++, thus allowing you to continue in C++ with 
your GUI logic close to where you loaded the QML to begin with.

I use a timeout to guard against QML errors should my loader stumble 
into poorly formed QML.

You can always try to handle the QMLEngine::warnings() signal, but that
is a work in progress.

I never set my Loader to be synchronous so that I never block the Gui 
Thread with QML loading operations.

Hope the idea resonates with someone in the list.

Cheers,

md

[Interest] Qt 5.5 DEB (or other install package) for Ubuntu 14.04 out there?

[Jason Kretzer]

Basic question.  I have a Qt 5.5 application that I want to install and run on 
Ubuntu 14.04.  However, the most recent Qt libs are not available in the 
standard repos.  Anyone know where I can obtain such things?  My little 
application is to be distributed as a DEB file but fails on installation due to 
the Qt lib version.

Am I out of luck here and have to build my own or does such a repo exist 
somewhere that would obviously not only include the Qt 5.5 but their 
dependencies as well?

Re: [Interest] Qt 5.5 DEB (or other install package) for Ubuntu 14.04 out there?

[Cédric CARRÉE]

Hi Jason,

I faced the issue with Qt 5.1 on Ubuntu 12.04. At that time packaged 
version of Qt was Qt 4.8. I had to build my own package for Qt 5.1. Then 
I switch to a greater version of Ubuntu to get a more up-to-date version 
of Qt. Maybe Ubuntu 15.10 does the trick.

Re: [Interest] Qt 5.5 DEB (or other install package) for Ubuntu 14.04 out there?

[Yuvraaj Kelkar]

Qt5 libraries do exist on Ubuntu 14.04.
If you have built your deb on 14.04, then the debhelper should have
put in the correct dependency information.
If you build on a version > 14.04 and try to run on 14.04 then your
debianization scripts need to be explicit about versions.

I used to do this by using a 14.04 VM. Now I use a 14.04 Docker image.
