Calendar in Qt via QML(Solved)

[actionking]

Very much thanks ,
It works.......What i have expected....But need to do some changes...If i click any date means,its color should change...I'm working....If any query means,i will ask u boss.thanks a lot

[JapieKrekel]

I'm glad 'it works'.

I do not know if you need any further help, I find it very hard to understand your replies.

So I'm guessing here, don't know if this is what you're looking for. If you want to change the color when the mouse is pressed and change it back when released the easiest in that case would be to give the mouse area an id and then use the mousearea pressed property to change the rectangle color.

 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 {
 anchors.centerIn: parent
 text: index + 1 - firstDay
 opacity: (index < firstDay) ? 0 : 1
 font.bold: isToday(index - firstDay)
}

MouseArea {
 id: dateMouse
 anchors.fill: parent
 onClicked: {
  var clickedDate = new Date( showDate.getFullYear(), showDate.getMonth() + 1, index + 1 - firstDay)
  console.log(clickedDate)
 }
}

}
}
}
}

On line 20 I added a property to 'remember' the original color.

I noticed that on line 6 you do color: "#303030" and later you do calendar.color="green", why don't you set the color of the calendar to "green" directly?

Please let me know if I can do anything else for you.

[actionking]

thanks boss..If i put that "green" color in starting itself means...Only for the current month,it will be working..If we pressed next icon means green color will be changed to some other color(defaultly "white"...I guess it so)
Actually i want to display the date in the format (dd/mm/YYYY)..How to do it...
Very pleased....

[JapieKrekel]

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

to do that.

[actionking]

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.

[JapieKrekel]

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

Thank you sir,
Whatever you have said,its right...Ya i have been working in Qml for quite 1 and half month only.....Not bit inexperienced..more inexperienced.....again problem arises...if i clicked new date means,it becomes yellow and the date becomes inisible, its showing correct date...But after clicking another date,previous clicked date too in same yellow colr and clicked date becomes invisible....what can i do?I'm trying sir....

Thank you very much sir..Its worked.....thanks for sharing your knowledge...Very pleased for your help..

Glad to help, if all is done, please close all your topics about the calander with [Solved] in front of the title. I believe you posted three of them.

Hey, thank you for this very helpful thread, that's a good starting base for a QML calendar.
Here is the same version using more modern layouts :
