Reduce space(h and v) between icon in QGridlayout

Dcqt

Hi
The below code displays some icons in gridlayout.

i trying to reduce the horizantal space between the icons , but i could not .

please give me a hint on what are the function i can use to reduce the space(H and V ) between the icons in a laid out in a gridlayout.

@QGridLayout controlsLayout = new QGridLayout();
QGridLayout *controlsLayout2 = new QGridLayout();
controlsLayout2->setHorizontalSpacing(0);
QWidget *widg = new QWidget;
setLayout(controlsLayout);// set to mainWindow
controlsLayout->addWidget(widg);
widg ->setLayout(controlsLayout2);

appWidget[app_no]= new QWidget();
appWidget[app_no]->setFixedSize(78, 78);

          q_Icon[app_no]=new QPushButton();
          q_Icon[app_no]->setFlat(TRUE);
          q_Icon[app_no]->setFixedSize(60,50);
          QPixmap pixmap(somepath);
          QIcon ButtonIcon(pixmap);
          q_Icon[app_no]->setIcon(ButtonIcon);
         label[app_no]= new QLabel(this, 0);
         label[app_no]->setMaximumSize(73,20);
         label[app_no]->setAlignment(Qt::AlignTop|Qt::AlignCenter);
         label[app_no]->setFont(font);
         label[app_no]->setText("<font color = 'white'>"+QString(label_text_list[0]));
         label[app_no]->setFrameStyle(QFrame::NoFrame);
         label[app_no]->setAttribute(Qt::WA_TranslucentBackground, true);

        appLayout[app_no] = new QVBoxLayout();
        appLayout[app_no]->addWidget(q_Icon[app_no]);
        appLayout[app_no]->setSpacing(0);
        appLayout[app_no]->addWidget(label[app_no]);
        appLayout[app_no]->sizeConstraint();
        appWidget[app_no]->setLayout(appLayout[app_no]);
        controlsLayout2->addWidget(appWidget[app_no], row_n, col_n, 10, 2, Qt::AlignTop|Qt::AlignLeft);@

Hi,

in your code you mix Layout and setFixedSize() method. Why?

Hi,

I want the size of button to be remain constant .
is it a wrong way to do, i really dont know much of Qt?
i just used by following some examples and some manuals on net.

my problem is , when the mainwindow is minimized the distance between icons is less, but when it is maximized the distance also increasing.
