Hi,

I'm facing difficulties in setting QSizePolicy to my widgets in QGridLayout.
I'm creating a custom time-selection widget, that has 2 QTextEdit, 4 buttons. My problem is the QTextEdit widgets and QPushButtons are not shrinking as desired.
PFB, the screenshot of the Timeselection Widget that I'm trying to develop -

This is max horizontal shrink

This is max vertical shrink
TimeSelection_Vertical Resize limit.png

Desired behaviour -
I need the horizontal shrink to be limited to text in QTextEdit without wrapping text(displaying in next line). And I need the vertical size to shrink upto row-end of the text.

Here the buttons are also not shrinking beyond the one I showed in 1st image. I need the buttons to be as small as possible.

As shown in the pic below, I need the exact idea to be translated to my widgets behavior.

Qt Code: 
  1. CTimeSelect::CTimeSelect(QWidget *parent)
  2.     : QWidget(parent)
  3. {
  4.     this->setLayout(&lyt);
  5.     this->setContentsMargins(0, 0, 0, 0);
  6.     lyt.setSpacing(0);
  7.     lyt.setContentsMargins(0, 0, 0, 0);
  8.     onInit();
  9. }
  10.  
  11. CTimeSelect::~CTimeSelect()
  12. {
  13. }
  14.  
  15. void CTimeSelect::onInit()
  16. {
  17.     timeDisp.setText("11:30");
  18.  
  19.     timeDisp.setFont(QFont("Lucida Console", 24, QFont::Bold, false));
  20.     timeDisp.setReadOnly(true);
  21.     timeDisp.setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
  22.     timeDisp.setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
  23.     timeDisp.setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
  24.  
  25.     timeUp.setText("+");
  26.     timeUp.setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
  27.     timeDown.setText("-");
  28.     timeDown.setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
  29.  
  30.     am_pm.setText("PM");
  31.     am_pm.setReadOnly(true);
  32.     am_pm.setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
  33.     am_pm.setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
  34.     am_pm.setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
  35.  
  36.     am.setText("^");
  37.     am.setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
  38.     pm.setText("v");
  39.     pm.setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
  40.  
  41.     lyt.addWidget(&timeDisp, 0, 0, 2, 4);
  42.     lyt.addWidget(&timeUp, 0, 4, 1, 1);
  43.     lyt.addWidget(&timeDown, 1, 4, 1, 1);
  44.     lyt.addWidget(&am_pm, 0, 5, 2, 2);
  45.     lyt.addWidget(&am, 0, 7, 1, 1);
  46.     lyt.addWidget(&pm, 1, 7, 1, 1);
  47.  
  48.     lyt.setColumnStretch(0, 1);
  49.     lyt.setColumnStretch(4, 0);
  50.     lyt.setColumnStretch(5, 1);
  51.     lyt.setColumnStretch(7, 0);
  52.  
  53. }
