@BlueMagnificent... Great job you're doing here... I remember a while back when I was trying to setup wxwidget too, anyway, I ended up going with Qt. its been great so far and I've been working on a project for a while now. But I'm having some difficulty achieving what I want with QPrintPreviewDialog... I'd post snippets if you can help me out.

I'll be glad to help out

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QLabel>
#include <QPrintDialog>
#include <QPrintPreviewDialog>
#include <QPrinter>
#include <QPainter>


MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::on_pushButton_clicked()
{
QPrinter printer;
//printer.setResolution(QPrinter::HighResolution);
printer.setPaperSize(QPrinter::A4);
printer.setOrientation(QPrinter::Portrait);
printer.setFullPage(true);




QPrintPreviewDialog *printPreview = new QPrintPreviewDialog(&printer);
connect(printPreview, SIGNAL(paintRequested(QPrinter*)), this, SLOT(print(QPrinter*)));



printPreview->setWindowTitle("Preview Dialog" );
printPreview->exec();
}





void MainWindow::print(QPrinter *printer)
{
QPainter painter(printer);



painter.begin(printer);
double xscale = printer->pageRect().width()/double(ui->centralWidget->width());
double yscale = printer->pageRect().height()/double(ui->centralWidget->height());



double scale = qMin(xscale, yscale);

painter.translate(printer->paperRect().x()+printer->paperRect().width()/2, printer->paperRect().y()+printer->paperRect().height()/2 );

painter.scale(scale, scale);

painter.translate(-width()/2, -height()/2);



ui->centralWidget->render(&painter);
}

What I intend to do is generate and print a report. I intend to design the report with Qt Creator, and then, sort of grab the form and print in A4 size. But I have a feeling I'm not going about it the right way... I saw QPdfWriter mentioned in a couple of places on the web, but can't quite figure it out.

pls can u tell me the qt version you download is it the one with mingw or the one with msvc . Pls i downloaded the one with msvc but the qt creator dosent compile it keeps telling me error i want to ask if i download the one with mingw will it work

mingw... I remember having similar problems too with the msvc compiler, I installed the mingw version & everything worked straight away...

tanks I will download another one with the Mingw and install it but I want to ask have u designed any application and have you finished with all the topics under the c++ language

I'm currently working on a simple record keeping app... & No, I'm nowhere close to finishing c++ topics, I'm still a beginner... If you can at least understand what classes & pointers are, I think you can start doing some things with Qt... While still studying your pure C++ materials...

Blue wxwidgets is totally IT. I dazzled during my defense thanks to wx. I will be using it for a very long time.

Thats great, wxWidgets is really a resourceful GUI lib when u get to understand it.
Congrats on ur successful defence

c++ is not a programming language of choice when it comes to GUI programming because even with the available languages (i have used Qt in the past) it's user interfaces can't be as visually appealing as those created with other .NET languages like c# and Vb.

but here is what c++ is great for
1. Game programming: c++ is the language of choice when it comes to creating game engines and it is the standard language used in the video game production industry. for people interested in becoming game programmers...feel free to check out the amazing training provided by game institute: http://gameinstitute.com/....it's really cheap compare to all the content you'll get but don't take my word for it...check it out yourself.

2. Operating system programming: well in case you didn't know the original version of the linux operating system was created using c++ and most other applications that interact directly with hardware require the use of C, c++, objective C...generally the C languages though.

3. Arduino programming: c++ works well with this.

Well it would had been better if u specified that the above was ur personal opinion

C# and vb is good for windows, its not really cross platform but if you want to say mono its not the same as windows you will have to make some small changes to your code while Qt is just one code.

Pls I have a problem with qt how can I add a form to my application pls. I did a dialog with my qt designer which gave me a Bleep.ui file pls how can I generate the Bleep.h and Bleep.cpp and how to use It on my app made with qt creator may God bless u all for your contributions thanks

[quote author=peterincredible post=31903147][/quote]

If I got you right, you want to use a form generated in qt designer in your application designed with the qt creator, right?

helo gud day, am into c++ programing, for sumtym now i have bin trying to do sum stuff dat involve the use of gui toolkit like wxwidget or qt bt i couldnt use dem. Though i concentrated more on the QT, i tried all i could, to make sure dat the qt work but all to no avail. When ever i compile my codes it keep giving me error. Plz i will be vry vry happy and grateful if u can help me out with the qt.
Plz guys help me. My numb nd my whatsapp numb is: 08036407597

Good to learn of your interest in C++
Can u please post the error message you encountered while building your application

my laptop has been down for sumtym now cos we dnt av power supply. For now we can only talk on phone. Thanks

I guess its best for us to communicate about the issue here so that other with similar problem can easy find it

Post the code here someone may correct it.

Hey guys.. i really commend all ur effort in this forum. Please j need u guys to help me explain how to QDir class member function path(). Thanks

give a nigeria guy stuff for free he calls it local I have ultimate. solution. but guess. what it is not for free

I am a bit confused as to what your question is about. Please can you explain better

pls i am working on an app pls i want to know by d tym i finish with d app how can i make it a stand allone app in exe format or any other format your reponse will be highlyy appreciated tanks

Which language are you building the app with and which libraries are you using?

If you are building with C++ and you are using any of the mentioned toolkits (wxWidgets or Qt) then your app is build directly as a stand alone executable. Note that if you want to distribute this executable you would have to distribute it along with the necessary dlls that it links with at run time

am writing it with c++ and i am using qt , i heard for u to be able to have a stand alone app u have to do a static building configuration or so can u help me explain dat and also i am also interested in mobile app can i use qt to develop a mobile app and also is there diff btw gui programming app and mobile app your contributions will be highly gratefull tanks

The information about doing static building configurations is not really right as such. You can have a standalone application whether you are using static or dynamic linking.

By linking statically it means that the qt codes referenced in your application are bound to your application executable during compile time, this means that you would'nt need to distribute any of your applications with additional qt based dependencies. The downside is that your application's executable size increases.

With dynamic linking, a reference to the qt library code (not the whole code) that your application uses is bound to your application during compile time. When you application runs it then loads the needed codes dynamically from the qt library (which on windows is a .dll file). The advantage of this is that your executable's size is far smaller than if it was build using static linking. The downside offcourse is that for you to distribute your application, you have to distribute it with the needed qt dlls else it won't run.


So in both cases your still have your stand alone executables, just that for dynamically links application you'll have to include the qt dlls while distributing it

Anybody using emacs here or cygwin?

for those dat are looking for a good qt text book for beginners download this book "foundation of qt development" and i promise u will be happy u were informed about this book

Hello,

I'm very much interested in wxWidgets. I've downloaded the source built it at the command prompt and also installed code::blocks to run it on.

But I'm having difficulty. I keep getting an error message: No such file or directory every time I try to build a (sample) program in code::blocks using wxWidgets.

I need help please!!!
