            <title>Qt 4.8.4 on MAC with openssl 0.9.8 Crash</title>
            <link>http://qt-project.org/forums/viewthread/28049</link>
            <author>gpazo</author>
            <description><![CDATA[We have an application that uses SSL to connect to a PostgreSQL (8.4) database server, when SSL is enabled on the server the MAC client specifically is unable to connect. This issue began after upgrading to Qt 4.8.4 from Qt 4.6.3 and the client seems to work perfectly without SSL enabled on the server but I&#8217;d like to get to the bottom of the situation.

	Qt Config: ./configure &#45;nomake demos &#45;nomake examples &#45;qt&#45;zlib &#45;qt&#45;libtiff &#45;qt&#45;libmng &#45;qt&#45;libjpeg &#45;qt&#45;libpng &#45;openssl &#45;I /Library/postgresql/include &#45;L /Library/postgresql/lib &#45;prefix /Library/qt &#45;plugin&#45;sql&#45;psql &#45;plugin&#45;sql&#45;odbc &#45;plugin&#45;sql&#45;sqlite &#45;arch x86 &#45;prefix&#45;install &#45;confirm&#45;license &#45;opensource

	Crash Log:
http://pastebin.com/5eZwVqik

	Error Context in terminal:
http://pastebin.com/j6zkSWkB

	Most of the time the application will crash immediately upon starting up, leaving very little room for debugging.  Does anyone have any suggestions or known&#45;issues with SSL and Qt 4.8?

	Thank you, 
Greg]]></description>

            <title>About QwtScaleWidget and QwtPlot</title>
            <link>http://qt-project.org/forums/viewthread/27985</link>
            <author>Nicholas</author>
            <description><![CDATA[i create a QGridlayout and place a QwtPlot in the center and four QwtScaleWidget at the side of Top, Bottom, Left, Right of the QwtPlot.
i initialized the four scales like below:
scaleTop &#45;&amp;gt; setScaleDiv( plot &#45;&amp;gt; axisScaleDiv( QwtPlot::xTop ) );

	But i found, the four scales are not matched with the plot.
The value range of the scales is ok, but the ticks are not aligned with the grid of the plot.
How could i do something to fix this?Thanks&#8230;]]></description>

            <author>BillWang</author>
            <description><![CDATA[Hello all,

       I am new to QT platform. I would like to develop a non&#45;web based Math Rendering with MathJax. It it seems someone has paved the way. See here [blog.qt.digia.com] Kent Hansen has already made the env.js working properly with QT script. However, due to my poor experience with QT platform, I couldn&#8217;t get the lib or plugin working.

	From Kent Hansen&#8217;s description:
Fully embed Envjs in the application: Pass the contents of env.js to QScriptEngine::evaluate(), and then call initializeEnvjsNatives(). You&#8217;ll need to add src/shared/envjsnatives.cpp to your application sources. &#8212;&#45;&amp;gt;&amp;gt;&amp;gt; before even putting the env.js in my console, how should I link env.js in .pro file?

	Also, where should I leave my MathJax.js?]]></description>

            <description><![CDATA[Hi everybody,

	I&#8217;m new to Qt and I&#8217;m using QCustomPlot to create a plot out of some informations. Now I want to click with the left mousebutton into the graph and want to get the coordinates of the position I clicked at. I couldn&#8217;t find any solution for it yet, but I can&#8217;t believe I&#8217;m the only one who wants to do this :). It seems like I&#8217;m missing something obvious. Can someone give me a hint?

	Thanks,

            <description><![CDATA[Hi all,
I would like to design GUI for microcontroller Arduino in Qt Creator. So I have looked at internet and found aQtLow (https://code.google.com/p/aqtlow/)
which has its own communication library dTxfrUSB for Arduino.
I wanted to use this for my project but I don&#8217;t understand how to use the dTxfrUSB in Qt GUI. I have implemented the library into code for microcontroller (Arduino) and now &#8211; how to read the data microcontroller sends to me per USB in my Qt GUI?
This is the dTxfrUSB code:

&amp;nbsp; &amp;nbsp; port&#45;&amp;gt;setDataBits&#40;DATA_8&#41;;
&amp;nbsp; &amp;nbsp; port&#45;&amp;gt;setStopBits&#40;STOP_1&#41;;


	and now I would like to read the coming information from Arduino. In Arduino code, I have variable dT.R[ 0 ] &#8211; dT.R[ 6 ] and dT.C[ 0 ] &#8211; dT.C[ 6 ] and I would like to use them in my Qt GUI as actual values (e.g. voltage on the device, it must be actual).
The dT.Run(); function in Arduino is called every loop so the values of dT.R[i] and dT.C[i] should be sent to me in Mhz takt. Will they appear in console as well? It is a pity I have forgotten my Arduino at work so I can&#8217;t experiment with it until Monday ;) Only to write the code.
How can I read the dT.R and dT.C please in Qt Creator? I will create for them widgets where they appear then.
Many thanks.]]></description>

            <description><![CDATA[Hi.

	Can someone help me installing QtSerialPort in Qt 5.0.2 (32 bit) &#8211; Ubuntu.

	Can you tell me all the steps, one by one? I&#8217;m new to Linux.

	I already tried using what is on http://qt&#45;project.org/wiki/QtSerialPort and some other hints from several posts, but i can&#8217;t make it work.
So it&#8217;s best to start from scratch.

	Thanks]]></description>

	As you know most KDE applications has two major options for KMainWindow &amp;amp; KXmlGuiWindow which is Configure Toolbars and Configure Shortcuts.

	Is there any similar OR alternative solution for Qt or I&#8217;ve to code them by myself?

            <title>QExtSerialPort: How to determine if a serial port is in use by another application?</title>
            <link>http://qt-project.org/forums/viewthread/27522</link>
            <author>maikel</author>
            <description><![CDATA[Hi,

	I use QExtSerialPort V1.2rc and I have the following problem:

	On Windows the function port.isOpen() returns TRUE if the serial port is in use by another or the same application, so you can not open it until it is released.

	On Mac OSX isOpen() returns FALSE, if the port is opened by another application and it is possible to open the same serial port and to send and read data, although the port is in use, messing up the communication.

	How can I avoid this? How can I determine if a serial port is in use by another application (opened for READ/WRITE) on Mac OSX?

	Thanks!]]></description>

            <title>Qt with Netbean &#45;&#45; C++ Development</title>
            <link>http://qt-project.org/forums/viewthread/27494</link>
            <author>bresser</author>
            <description><![CDATA[Hello,
I am using Qt inside of Netbean. I just newly installed it. I looked at a few of Netbeans tutorials for Qt, and it just puzzled me more. I know how to make appearance stuff. So I can design the form I just don&#8217;t understand how to make the form do what I want. 

	So what I am making is a program that I enter a message into. Then I want it to when I click the button reference a LibreOffice Spreadsheet(oh yeah I&#8217;m on Ubuntu if that is important). I want it to look at the spreadsheet and A1 will be the letter I typed in, but A2 will be a different letter. So pretty much it translates an english message into gibberish. 

	To go into further detail:

	Lets say
A1A2 A  V P  Q L  1  E  7 

	So for my example. In my first box I would put Apple
Then I would hit translate button.
It would look at this spreadsheet say ok A = V P = Q L = 1 E = 7
so Apple = VQQ17
Pretty simple cipher. But no one will spend enough time trying to break it. 
But right now I&#8217;m just focusing on how to make the button reference the spreadsheet and change the letters.]]></description>

&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &#125;
&amp;nbsp; &amp;nbsp; &#125;
&#125;


	If I call the external function &#8220;capGetDriverDescriptionA&#8221; from 0 to 2 all works well. I obtain the name of the two cameras correctly.

	But if I go over 2 the program goes to crash.
According to msdn the function &#8220;capGetDriverDescriptionA&#8221; returns true if the camera exists and false if the camera does not exists. If I comment out the row &#8220;ui&#45;&amp;gt;textEdit&#45;&amp;gt;append(QString(szDeviceName));&#8221; the program does not go to crash and I can query the function from 0 to 9.

	Is this possible? How can I obtain the cameras list?

	Now I&#8217;m using Qt 4.8.4 with mingw.]]></description>
