Little aplication that translate a string in Arabic and after save this Label in BMP
-
Hi all,
I'm new in C++/QT and i need your help because this is my first application:
I must make an application in Arabic that translates a text string, then:
INPUT -> Text BoxOUTPUT -> Label Arial 8
After this Label i must be exporting as BMP image..There is an example where i can view source code?
thanks for help.. -
do you will use the object "tr". but i never use that...
-
How do you think you'll implement the translation part? I mean: do you have a dictionary or something available?
The rendering to an image is the simple part... Just create a QImage, create a QPainter on that, and render your Arabic string using QPainter::paintText()
-
using this object you can translate some languages for the Qt.

Thanks for your answer.
I don't know how implement the traslation part.. A dictionary is ok.. But the problem is that in Arabic the shape of the letters change depending on the next letter, for example:"student" is طالب but it is formed by this letter:
ط ا ل ب
Note like change form for example this: ل --> لب -
Sorry, no. I'm not going to do your homework for you. However, if why don't you just give it a (serious) try, and post your code when you get stuck? I'm sure somebody, perhaps myself, will be willing to help you out then. But you have to show that you're willing to put in effort of your own first.

Why don't you give it a try and get started? We're not here to hold your hand every baby step of the way, but in general, we're a friendly bunch that are ready to help you. I already gave you a pointer on where to get started for the rendering stuff: [[doc:QImage]]. Note that that class also supports saving to file, including .bmp files (through a plugin, but that's of secundairy importance right now).

ok.. then start with :
@
#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QPainter>int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
QImage myImage;return a.exec();}
@
to be continued..edit: please use @ tags around code sections; Andre

OK, great. So now you have a QPainter on your QImage. Time to use that painter for something useful, right. Can you spot a useful method for painting text in the QPainter documentation?
Perhaps you should give your image a size too... It is hard to paint if your canvas is too small, after all.

enaud84 - I don't think what you people are doing in this threat is going to work any time soon. If your English is decent go and read a book on Qt, it will take you a while but you will actually learn something and be able to develop on your own without needing to be pushed every step of the way.
Here is a link to a GOOD and FREE book on programming with Qt, it also contains the basics of C++ so it is a very good learning resource:
http://ptgmedia.pearsoncmg.com/images/9780131879058/downloads/0131879057_Ezust_book.pdfAs you get familiar with C++ and Qt you will find it much easier to work with the Qt documentation as well. I can tell you cannot get your way around the Qt DOC since you claim you cannot find a QPainter method for drawing text, and there is a whole bunch of overloads of the drawText() method.
Good luck, be patient and consistent and you will be rewarded.

[quote author="enaud84" date="1333400351"]Hi,
how set size of Image?
I not find method for painting text in the QPainter documentation :(Thanks[/quote]
No, I understand that. But you would not expect to control the size of a real painting canvas via your brush or pencil either, right? Perhaps you should look at the [[doc:QImage]] documentation for a way to set the size of the image...
