Label

[hajo93]

I want to put in a picture in my QT application.
I made an empty label and called Label_pic
when I go in manwindow.cpp and write
"ui> Label_pic-> setPixmap (pix) for i an error where it says" no member 'label_pic' in 'ui :: mainwindow "1303613037

QPixmap pix("C:\QT Nyeveier/Nyeveier.png");
ui->label_Pic->setPixmap(pix)

and then i get this error: no member named 'label_Pic' in 'Ui::MainWindow'


<widget class="QLabel" name="label_Pic">
<property name="geometry">
<rect>
<x>20</x>
<y>20</y>
<width>151</width>
<height>221</height>
</rect>
</property>
<property name="text">
<string/>
</property>

This is from my mainwindow.ui

Manually run qmake (rightclick on project -> run qmake) and re-compile the project a few times. Sometimes there are hickups.

Yes, I agree. I don't see anything wrong with the code or ui file, and support for "png" format is built-in and does not require a separate driver. So probably your ui file did not get compiled after you added or changed the name of the QLabel item.

Also, make sure when you use a backslash ("") in string that you "escape" it: "C:\\folder\\filename.png" If you don't it will treat a "\f" as a special character and the actual filename string that gets passed to setPixmap() will be incorrect.
