Qt Creator and other tools

I think there was some work on the codeblocks cmake generator (which we also use). So maybe a newer version does work better already:-)

Tobias,

I was completely wrong on my statement that I successfully compiled the QT4.7.3 with x64 MSVC++ compiler. I found out that I couldn't even get the x64bit components installed in the first place. (I had failed to install those components on VisualStudio 2010 Express version, and didn't know that I had.)

In short, QT libraries I tried to used were not 64bit binaries.

I found a simpler way:
@d.putValue(extractCharArray(item.value["string"], 40))@

Ok. What do QMAKE_HOST.arch and QMAKE_TARGET.arch contain for your setup?

Oh my god, after reading a bit more on it, i really was making silly mistakes. Thanks guys

Thanks, got it.
The correct line is:
@wave w; //where wave is my QMainWindow class
w.setWindowIcon(QIcon("/image.jpg"));@

Here is the solution:

mythread.h:
@#ifndef MYTHREAD_H
#define MYTHREAD_H
#include <QThread>

class MyThread : public QThread
{
Q_OBJECT
protected:
void run();
public:
explicit MyThread(QObject *parent = 0);
};
#endif // MYTHREAD_H
@

mythread.cpp:
@#include "wave.h"
#include "mythread.h"

MyThread::MyThread(QObject *parent) :
QThread(parent)
{
}
void MyThread::run()
{
onWriteLoop();
}@
wave.cpp:
@wave::wave(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::wave)
{
ui->setupUi(this);
setup();

thread = new MyThread();

}

wave::~wave()
{
delete ui;
delete thread;
}

void wave::on_pushButton_clicked()
{
//Generate
freq = ui->frequency->text().toDouble();
ampl = ui->amplitude->text().toDouble();
thread->start();
ui->pushButton->setEnabled(false);
ui->pushButton->setStyleSheet("background-color: gray");
ui->pushButton_2->setStyleSheet("background-color: rgb(255, 192, 192);"
"color: red;");
ui->pushButton_2->setEnabled(true);
}

void wave::on_pushButton_2_clicked()
{
//Terminate
thread->terminate();
ui->pushButton_2->setEnabled(false);
ui->pushButton_2->setStyleSheet("background-color: gray");
ui->pushButton->setStyleSheet("background-color: rgb(192, 255, 208);"
"color: green;");
ui->pushButton->setEnabled(true);

It actually seems to be a Qt bug. The new bug ID is "QTBUG-20925":https://bugreports.qt.nokia.com/browse/QTBUG-20925

But it can be in the same directory where I put now? Or I have to put it outside?

I would personally not put the command into the Qt Creator settings at all: You do not want to keep re-running this for each and every build!

So just run it once from a terminal and then only add the "make" step to Qt Creator. That should work fine.

Well, this works. It's rather unsatisfying though, since this means everyone on the team needs an alternative build rather than using the standard binary provided on the qt download page. Also seems to cause a crash when loading other plugins, presumably because they're compiled with 4.7.4.

solved. areas had different values as it was declared again.

Basically you click in front of the line where you want to place a bookmark. Then you click the green arrow button with a bug on it. Use the buttons to step in/out code blocks.

You can read about it in the Qt Creator manual too.

Did you try to debug it and step through to check what happens? You have an endless loop here (where is isTrue set to false?)

If you provide a full, runnable and debuggable example, perhaps others could also try with the debugger...[/quote]

Hi, yes line 25 has executed. I just debugged it and there seems to be no issues.
isTrue is set to false under my second pushButton function (pushButton2) which is to terminate the loop. I have actually solved the issue, it doesn't terminate anymore. There are no more errors, but now, the problem is when I hit the pushButton, it doesn't generate any sine wave:( Definitely, here is my wave.cpp:

Hi,

As the loop executed on a button press, which means runs inside the main event loop, tzhe second button press will never be executed, as the main thread is blocked.

Regarding the other thing, I have no idea, as I have no experience in sound card programming...

ok. Thanks for your help. Much appreciated.

Have a look at the "diagram scene example":http://doc.qt.nokia.com/4.7/graphicsview-diagramscene.html I think this is what you want.

Fortunately I remembered a previous topic you made so I could guess you're drawing on a QGraphicsscene. Please provide more information if you want specific answers.

I'll leave Volker to answer for the Mac side of things but on Windows I use NSIS to build an installer. I've already told you how to structure your installation dir on Windows but here it is again:

@
$INSTALLDIR
$INSTALLDIR/application.exe
$INSTALLDIR/$QTLIBS
$INSTALLDIR/{libeay32.dll, ssleay32.dll, libssl32.dll}
$INSTALLDIR/qca2.dll
$INSTALLDIR/crypto/qca-ossl.dll
@

This really is much less work than trying to compile all of these projects into your application.

Thanks again!

I added a Link to this topic there to avoid the developers have the same misunderstanding as we had here ;)

And i voted for it!

are you really literally using "CONFIG" as scope? if so, what do you want to achieve?

This works for me, it's not pretty, but now I can say "loop"

@
for ( int ii = 0 ; ii < max; ii++ ) +[{ESC}o+]{ESC}ko
@

Now all I need is a little processor to turn actual code into a Dragon macro :)

Or just hit <Escape>
