Unsolved Make changes in buttons' shapes and sizes in a gridlayout
-
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:
http://uploads.im/M1KOV.pngFirst 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?

Re: Make changes in buttons' shapes and sizes in a 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.

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.
