Make changes in buttons' shapes and sizes in a gridlayout

tomy

Hi guys,

This is a for loop of the code positioning and giving sizes to 22 buttons:

for(int i=0; i<texts.size(); ++i)
      {
         QPushButton* button = new QPushButton(texts[i]);

         connect(button, SIGNAL(clicked(bool)),
                 signalMapper, SLOT(map()));

         signalMapper -> setMapping(button, texts[i]);
         gridLayout -> addWidget(button, i/5, i%5);
      }

The result is in as follows:

First I want to make buttons smaller.
Then to arrange them by manually giving them coordinates.

How to do these please? Should I firstly remove the gridlayout?

One way to do it:

Pass the parent 'this' during initialization of the buttons and then move them as desired.

QPushButton** buttonArray;
buttonArray = new QPushButton*[22];

for(int i=0; i<texts.size(); ++i)
      {
         buttonArray[i] = new QPushButton(texts[i], this);

         connect(buttonArray[i], SIGNAL(clicked(bool)),
                 signalMapper, SLOT(map()));

         signalMapper -> setMapping(buttonArray[i], texts[i]);
      }

buttonArray[i]->move(xPos, yPos);

As for making the buttons smaller, take a look atQWidget Class for setting max or fixed sizes.

@Carmoneer
Thank you. I set fixed size for the buttons and they appear better now.
But about positioning, your solution is a bit advanced for me as a newcomer to Qt.

Please read this scenario:
Can't I use a vector of strings and then put the strings ("2", "3", "+", "/" and the rest) into it and by a for loop call a function for the work?

That way I could set the size and position individually for each button manually.
