Is Qml Calendar component going crazy? -

-

before open bug qt project, i'd ask if i'm doing wrong or qml calendar going crazy.

it follows code can used test it:

import qtquick 2.5 import qtquick.window 2.0 import qtquick.controls 1.4 import qtquick.controls.styles 1.4 import qtquick.layouts 1.1  window {     visible: true     width: 1024     height: 768      columnlayout {         anchors.fill: parent         anchors.margins: 8          calendar {             id: calendar             layout.fillwidth: true             layout.fillheight: true             weeknumbersvisible: true             selecteddate: new date("2015/01/01")             framevisible: true             focus: true              onvisiblemonthchanged: visiblemonthchangedref.currdate = visibleyear+"/"+visiblemonth             onvisibleyearchanged: visibleyearchangedref.currdate = visibleyear+"/"+visiblemonth         }          label {             id: visiblemonthchangedref             layout.fillwidth: true             property string currdate: ""             text: "onvisiblemonthchanged -> " + currdate             component.oncompleted: font.pointsize = font.pointsize*2         }          label {             id: visibleyearchangedref             layout.fillwidth: true             property string currdate: ""             text: "onvisibleyearchanged -> " + currdate             component.oncompleted: font.pointsize = font.pointsize*2         }     } }

easy going, start application , you'll see calendar couple of labels report information visiblemonth , visibleyear provided calendar component. labels filled accordingly onvisibleyearchanged , onvisiblemonthchanged of calendar. selected date 2015/01/01.

well, go of month towards 2014.

the onvisibleyearchanged looks right while accessing visiblemonth , visibleyear properties of calendar, while onvisiblemonthchanged looks me living in far future.

now, try move on of month towards 2015.

again, while onvisibleyearchanged still behaving right way, onvisiblemonthchanged accessing calendar component sitting in past.

you can go , forth on new year , function reacting signal onvisiblemonthchanged never behave looks me invoked once internal properties have not been set yet.

that said, doing wrong , problem within code (of course, 1 above small example more complex project) or i've found bug in 'calendar` component , should proceed opening ticket qt project?

even though looks bit strange me asking modify component, being notified it's updated, find changes have been partially set (a kind of work in progress notification), that's it.

it seems error in expectations. :-)

once month moves on or on year (that is, december january , vice versa), calendar component correctly updates property visiblemonth , property visibleyear.

anyway, no guarantees corresponding signals (onvisiblemonthchanged , onvisibleyearchanged) emitted once internal representation has been updated whole.

actually, former emitted when changes second property still pending, querying visibleyear property in listener ends wrong year (or @ least, 1 not updated yet).

as example of solution, user of component can work around odd behavior attaching listener both signals, though suspect out there better solution waiting me.

i'll manage find alternative approach. thank of responses.
