            <author>Deleted Member # 1e05d</author>
            <description><![CDATA[I was curious ifI could get some idea on how to get started on my project.  Here is a brief description:

	&#45; Should have some buttons or menu keys that when pressed should show different things
like system health or battery status

	&#45; Should have a space which will display what the user types

	&#45; Should have area that displays a system clock.

	Now I am a true Novice in this so I am having ahard time getting started.  Things I am getting stuck are:

	1) If a menu button has different functions popping up, like battery status, system status(ie what mode the system is in).
they all would be a different program.  How do I put these together?  For example, I can look at the Battery Status example that comes with QT SDK, but how do I implement it for my project?  HOw do I just use the progress bar and not the whole nokia phone showing up on my project?

	2) Same with system clock.  I look at the digital clock example, but how do I make that part of my window?

	Thanks in advance for your help.]]></description>

            <title>Database Plugin for Qt Designer</title>
            <link>http://qt-project.org/forums/viewthread/16436</link>
            <author>Agroni</author>
            <description><![CDATA[In 1993 (almost 20 years ago), in IBM Visual Age I could drag a column name (of a DB/2 database) and put in a dialog it would automatically create a Label and an Line Edit, associate signals and slots.

	I could see database signals and slots and I could VISUALLY link them to the widgets on the form or to the menu items.

	What I want Qt Designer initially to do through a new plugin, is to provide a means to navigate to a certain table in a database so that the user (programmer) can pick what columns to appear on the dialog. The plugin would generate UI and C++ code and update the dialog in the designer with new Labels, Line Edits all using the QDataWidgetMapper. 

	If there is a group working on something like this I would like to join. Please let me know. Otherwise, I will start doing something like this myself and I would welcome anyone to join me.

            <title>QML Themeing</title>
            <link>http://qt-project.org/forums/viewthread/16341</link>
            <author>aalpert</author>
            <description><![CDATA[The historical approach to theming (Widgets) was a style plugin or style sheets that allowed you to go through a large number of customizable parameters when a QWidget went and drew itself. This was great for the monolithic widgets and for native theming, but I don&#8217;t think it will work in QML simply because we don&#8217;t have monolithic widgets. So if no other solution comes up for themability (including platform theming), it shouldn&#8217;t be too hard to recreate the QWidget library for QML ;) . (side note: since they often have properties already, you&#8217;d probably get most of the way there by making QWidget inherit QQuickPaintedItem). But I&#8217;m really hopeful that QML empowers a more flexible approach than the monolithic widget set.

	So let&#8217;s list the needs of theming in QML, and brainstorm some solutions that can really take advantage of the new technology. Here are the needs I culled from the mailing list discussion:

	
		One source, multiple target platforms
		Change the appearance of standard controls in my application
		Style QWidget and QQuickItem UIs with the same code
		Inside QML items, draw native controls without using QML
	

	Possible solutions I culled from the mailing list discussion:

	
		Centralized Convention on API
		Object with centralized properties
		Theme manager like QStyle/Style sheets
	

	Can anyone think of further needs, or other possible solutions?]]></description>

	I&#8217;m not sure this is the correct place for my question, so if anyone find it&#8217;s not the correct place, please, tel me (and where ;&#45;)).
My question is about Qt sources, and more precisely &#8220;corelib_global.h&#8221; (which can be found in &#8220;src\Plugins\qmldesigner\designercore\include&#8221;)
I would like have a little more information about what is mentioned in it :
// Unnecessary since core isn&apos;t a dll any more.
//#define CORESHARED_EXPORT


	I would like to know the reason why it was chosen to remove this define.
Was it a technical restriction ?, really justified or just some clean up ?
Consequence is that it is now impossible to use the core services from a plugin (Or do i miss something and there is a way I don&#8217;t know)

	Hope someone could help me, or give me clues to find information
Thanks

            <title>QML Property Bindings vs: States</title>
            <link>http://qt-project.org/forums/viewthread/14850</link>
            <author>FlyingSheep</author>
            <description><![CDATA[Hi all

	I have a software engineering question:

	For the past few weeks I have been working on an app for my Nokia N9 in order to learn QML. At the heart of the app is a GPS element.

	The GPS can be either on or off. Depending on this &#8220;state&#8221;, at least 5 child / sibling elements change their appearance. e.g buttons and menu items change from active to inactive, labels change colour etc.

	In my first implementation I achieved this via 2 states, which changed the element properties via PropertyChanges elements.

	However today it has occurred to me that I could achieve the same effect by using property bindings in the child / sibling element properties &#8211; binding these to the GPS elements  &#8220;gpsOn&#8221; property.

	Both of these approaches work. The question is, which approach is better from an software engineering point&#45;of&#45;view, and why?

	Do I give central control to a QML State, which then needs to know about a list of element properties, or should each element have control over its own properties by binding these to the GPS element as required?

	In my example the state model is simple &#8211; only 2 states (on and off), and the elements that need to change their properties are by their very nature closely coupled to the GPS element.

	Your thoughts are welcome.

	Chris]]></description>

I&#8217;ve never built any app and have no idea how to, but intend to learn soon, but no idea how soon. Although i would really love to see and test these ideas i have, only thing needed is some1 t build it.
1. N8 has dual mics but only records mono, stereo would be amazing.
2. N8 has fm transmitter and was thinking of a kind of so to say kareoke app. Speak on the phone mic while it transmits to a radio, while a sound track plays in the background via the music player. Would be a winner.
3.used holospeed? Screen is flipped vertically, has the speed, when looked at in the windscreen of the car, can see your speed and road easily, now if maybe an app to flip the whole phones user interface and use them the same in the car, or atleast with the ovi maps.
4. Split screen. Used road pilot? Has the speed trap cameras mobile and fixed. Now maybe while the maps are at the top, this road pilot is at the bottom t warn u?
Anyone interested?]]></description>

            <description><![CDATA[Hello to the whole forum,

	this is my very first post. I just want to do some brainstorming with this one.
My new project started and I am looking to do a little GUI where I parse some code (UVM testbenches in this case), recognize the classes within the code and create block diagrams out of that.
Every class should have a block diagramm with its inputs and outputs.

	After that it should be possible to drag those block diagrams around and connect them to a DUT via clicking the ports of one block diagram and then one port of another one.
QT should recognize these ports and create code out of it, when clicking the &#8220;create TB&#8221; button&#8230;

	Thats my rough idea. Now my question is:
Do you think this is possible (I think so) and did anyone do something similar till now or has a idea of how to do this?

	Thank you so much!
I will post any success in this forum.

	Regards,
JRS]]></description>

            <author>bms20</author>
            <description><![CDATA[Guys,

	I&#8217;m contemplating developing a &#8220;feature unlock&#8221; system for a Qt application I have in mind, and am wondering if this would be of value to anyone else doing Qt stuff.

	The application idea I have in mind is (as of yet poorly formed) however, the way the business will make money is by selling unlocks to end&#45;users; e.g. &#8220;for a dollar more, unlock this feature&#8221;.  The idea isn&#8217;t to be greedy, just earn enough to put food on the table, and prevent me from having to take a &#8220;real job&#8221; again :).

	The client side would use signed unlock files (e.g. like license management), the transport for these files would be https using Qt&#8217;s stack, and the back end would be fairly standard web technology (an ACID database, web application stack, pluggable payment gateway).

	My questions therefore, are:
	
		Would this be of benefit to you or your application?
		Would you pay for such a library and associated web&#45;backend system (e.g. where you setup your own hosted system&#41;?
		Do you know of other similar systems out there?
	

	Thanks,

	&#45;BMS

            <link>http://qt-project.org/forums/viewthread/12843</link>
            <author>rickst29</author>
            <description><![CDATA[The purpose of these classes would be to provide support to KDE for many feature requests&#45; requests which ask that mouse buttons be configurable as shortcut Invocation tools, in a way analogous to QKeySequence keystroke combinations.

	I have considered making an attempt to configure buttons into QKeySequence itself, and dislike that approach for 3 reasons:
	
		QKeySequence is already quite complex for users to deal with; adding Mouse Click,  DoubleClick, and (especially!) the holding of one mouse button while clicking ANOTHER mouse button into QKeySequence definitions would be awkward. Powerful, yes. But AWK!
		The Class itself is large and complex, because Qt supports many keyboard layouts. I am simply incapable of enhancing that Class in such a big way, without huge risk of introducing Bugs. (I&#8217;m simply not good enough to program all of that.)
		At the UI level, in KDE, Configuration of &#8216;KHotkeys&#8217; and the &#8216;Configure your Mouse&#8217; applications are already separate. It would be another large effort in KDE, to put these separate programs together as one module.
	

	In my own mind, I can&#8217;t justify the creation of a large, complex, keyboard+mouse combination. Handling shortcuts with the mouse alone, NOT involving the keyboard, seems about 80% sufficient for everything I personally want. (Especially because I&#8217;m including Doublick versus Click as separate Shortcut&#45;able Input actions, and with &#8220;hold one button, click another&#8221; capability providing nearly another full set of &#8216;virtual buttons&#8217; as Shortcut&#45;able Input actions.) Besides, I don&#8217;t have adequate programming skills to do the job. Within Qt5, this needs to be FINISHED in about 3 weeks, in order to fit with the Qt 5.0 Development schedule, there&#8217;s no way for me to understand, code and test modifications to the large and complex Classes which control the Keyboard logic..

	There is another, completely different idea on the Table, which would present the shortcuts as DBUS messages.  I may have the wrong impression of that scheme, but feel that it would take over at the shortcut Messaging level using DBUS as an alternative to Qt Signals/Slots.  It would not be using D&#45;Bus at the low level recognition of QKeySequence sequences, and Qt MouseEvent recognition of shortcut button events and combinations. I feel that DBUS messaging at either the character&#45;by&#45;character Keyboard Event layer, or it&#8217;s mouse button equivalent, would be too slow, creating massive delays and overhead.

	If I&#8217;m correct about this other Idea, then it could be done at a later time&#8212; still building upon current &#8216;QKeySequence&#8217; and QMouseShortcutEvent&#8217; processing for doing work at the high throughput, low overhead Device Input layers. If I&#8217;m wrong, then someone else needs to step up immediately&#45; because I can&#8217;t, and won&#8217;t even try, to re&#45;program the shortcut system with D&#45;Bus working at low&#45;level input event layers of Qt. IMO, it&#8217;s too radical, AND I&#8217;m not smart enough to do that.

	Here are some reference bugs from KDE:
https://bugs.kde.org/show_bug.cgi?id=96431 (Shortcuts in general.)
https://bugs.kde.org/show_bug.cgi?id=48062 (Now limited to a particular A18 feature; most of the votes were actually for Bug 96431).
https://bugs.kde.org/show_bug.cgi?id=34362 (The prerequisite, already done in Qt5, to support ALL of the buttons on &#8216;gaming&#8217; mice.)

	And, here is a reference to the D&#45;Bus idea (which I plan to ignore, sorry):
http://neverendingo.blogspot.com/2010/11/matter&#45;of&#45;control&#45;state&#45;of&#45;input&#45;device.html 

	
		One goal of this feature would be better A18 (accessibility features). This item, KDE bug 48062, calls for mouse button events to Toggle keyboard modifiers&#45; allowing both one&#45;handed and zero&#45;handed KDE Users to take their time in executing a KEYBOARD Modifier&#45;Key sequence, while pressing with only one finger (OR equivalent button pressing tool) at a time.
	

	Any comments, ideas, or advice on YOUR issues&#45; PLEASE feel free to add a post to this Thread, I WILL read everything! (Todd, inventor of the D&#45;Bus concept&#45; that especially goes for you. Please chat here!) And if there are any volunteers to Lead, or to assist me in stumbling around with this code, my special thanks&#45; in advance :))]]></description>
