Calendar in Qt via QML(Solved)

JapieKrekel · wrote on 2 Jun 2013, 13:21

You should be able to use
@
console.log(Qt.formatDate(clickedDate, "dd/MM/yyyy"))
@

to do that.

thank you sir for your immediate response.....But another problem arises..If i clicked new date means,it should come to Bold letter(yellow color)..Likewise if i clicked some other date means,now it should become bold letter and previous clicked date should go to normal one.

I should say that the code is becoming a little bit ugly. I would use a component with states for each day rectangle, but to illustrate how it can be done here an example.

I'm happy to help, but I get the feeling you're a bit unexperienced in QML, maybe it is wise to first do some reading "QML intro":http://qt.digia.com/Product/Learning/Education/elearning/online-training/Qt-Essentials---Qt-Quick-Edition/#.UatX1EA5nfI

@
Item {
id: dateGrid
width: parent.width
anchors.top: dayLabels.bottom
anchors.topMargin: 5
anchors.bottom: parent.bottom
property int currentActive: -1
Grid {
columns: 7
rows: dateLabels.rows
spacing: 10

Repeater {
id: repeater
model: firstDay + daysInMonth
Rectangle {
property bool highLighted: false
property color normalColor

Component.onCompleted: {
 if (index < firstDay)
  normalColor = calendar.color="green";

 else
 {
  if(isToday(index-firstDay))
     normalColor = "yellow";
  else
   normalColor ="#eeeeee"
 }
}
color: dateMouse.pressed?"blue":normalColor
width: (calendar.width - 20 - 60)/7
height: (dateGrid.height - (dateLabels.rows - 1)*10)/dateLabels.rows

Text {
 id: dateText
 color: highLighted?"yellow":"black"
 anchors.centerIn: parent
 text: index + 1 - firstDay
 opacity: (index < firstDay) ? 0 : 1
 font.bold: isToday(index - firstDay)  || highLighted
}

MouseArea {
 id: dateMouse
 anchors.fill: parent
 onClicked: {
  var clickedDate = new Date( showDate.getFullYear(), showDate.getMonth() + 1, index + 1 - firstDay)
  console.log(Qt.formatDate(clickedDate, "dd/mm/yyyy"))
  if (dateGrid.currentActive != -1) {
   // unselect it
   repeater.itemAt(dateGrid.currentActive).highLighted = false;
  }

  if (!isToday(index - firstDay)){
   highLighted = true
   dateGrid.currentActive = index
  }
 }
}

}
}
}
}
