stylesheet question

[gt.beta2]

Hi,
Imagine i have a Dialog (myDialog) with 3 QLineEdit objects: lineEdit1, lineEdit2, lineEdit3. I am using QtDesiner so i have 4 files:

• main.cpp
• myDialog.h
• myDialog.cpp
• myDialog.ui

If i want to apply a red color to the background off all lineEdits in the application e use, in main.cpp the following:

app.setStyleSheet("QLineEdit { background-color: red }");

app.setStyleSheet("QLineEdit { background-color: red }");

To copy to clipboard, switch view to plain text mode 

Now supose i want to apply other stylesheet color as the Dialog level. Where showld i place the code:

myDialog->setStyleSheet("QLineEdit { background-color: yellow }");

myDialog->setStyleSheet("QLineEdit { background-color: yellow }");

To copy to clipboard, switch view to plain text mode 

?
Thanks

myDialog->setStyleSheet(" background-color: yellow "); should do it.
When specifying QLineEdit in that line, it means for all line edits in that dialog

humm ... i don't think i explained myself well.
Imagine this situation:

#include <QApplication>
 
#include "Dialog_1.h"
#include "Dialog_2.h"
 
int main(int argc, char *argv[]){
	QApplication app(argc, argv);
 
    //apply stylesheet at application level
    app.setStyleSheet("QLineEdit { background-color: red }");
 
    Dialog_1 *dialog1 = new Dialog_1;
    Dialog_2 *dialog2 = new Dialog_2;
    dialog1->show();
    dialog2->show();
    return app.exec();
}

#include <QApplication>

#include "Dialog_1.h"
#include "Dialog_2.h"

int main(int argc, char *argv[]){
	QApplication app(argc, argv);

    //apply stylesheet at application level
    app.setStyleSheet("QLineEdit { background-color: red }");

    Dialog_1 *dialog1 = new Dialog_1;
    Dialog_2 *dialog2 = new Dialog_2;
    dialog1->show();
    dialog2->show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Both dialogs will show the color red on all lineedits, right?
Now imagine that dialog 2 is meant to be an exception, and i can not edit main.cpp.
Where in the .h, .ui or .cpp do i apply the overriding stylesheet?
Hope this makes any sense

Use selectors, for example object name.
