Image loading

[Stanfillirenfro]

Hi!

I am trying to get the path top a QImage for my application.
I did as followd:




QPixmap image;

image.load(QCoreApplication::applicationDirPath() + "/Desktop/myImage");



My problem is that I can not load any image.

What could be the problem? I will appreciate any help.

Many thanks in advance.

Where is the image name ? "myImage.png" , myImage.jpg ?? which one ?

Also what is the output of QCoreApplication::applicationDirPath() ?

Many thanks aamer4yu for your reply.
The image name should be myImage.png.
Have a look please. When I proceed as followed, I do not need to add ".png", and I can have the image loaded. But I do not want to go this way.


image.load("C:/Users/Desktop/myImage");

Even by writing myImage.png, there is no change.

I have created a label on which th image should appear as followed:

m_image = new QLabel(this);
m_image->setPixmap(myImage);

Are you sure you know what QCoreApplication::applicationDirPath() returns ?

[Stanfillirenfro]

Thanks Lesiok!

Yes, QCoreApplication::applicationDirPath() returns the directory that contains the application executable.

Please put a qDebug() for QCoreApplication::applicationDirPath() value...

Thanks aamer4you for your reply.

I am instead trying to proceed like this:


QDir dir;
dir.setCurrent("C:/Users/File/Desktop/imageFile");
image.load(dir + "/myImage");


This does not function. Could you please have a lokk and give me an advice?

Many thanks in advance.

Can You show us what is FULL path to file myImage and what is result of QCoreApplication::applicationDirPath() ?

[Stanfillirenfro]

Hi Lesiok!
Of courses!

The initial idea was to load different images from a list, each image being represented by its name. So I had to get to the file in which the images are stored and to select an image. To be able to change the name of each image in the path, I thought I could use QCoreApplication::applicationDirPath(), but unfortunately I failed.

I finally proceed as followed:



QStringList listImages;
QString str = "C:/Users/File/Desktop/imageFile/";

for(int i = 0; i<listImages.size(); i++)
{ if(listImages[i])
str.append(listImages[i])
image.load(str);

m_image = new QLabel(this);
m_image->setPixmap(image);


On this way I could solve my problem.

Thanks for your attention.
