Solved using alignment enum in an array
-
Hi all -
I have a multicolumn table used in several places. The caller can specify column widths by overriding some properties, which are defined as follows:
property int cellWidth: 200 // or whatever property int widthCell0: cellWidth property int widthCell1: cellWidth property int widthCell2: cellWidth property variant columnWidths: [widthCell0, widthCell1, widthCell2] Repeater { Column { Rectangle { id: columnRect width: if (index < currentData.length) { columnWidths[index] } else { cellWidth } ...
This works fine. But when I attempt to apply a similar solution for alignment, I get an error.
property int aligncell0: Text.AlignLeft property int aligncell1: Text.AlignRight property int aligncell2: Text.AlignLeft property int columnAligns: [alignCell0, alignCell1, alignCell2] ... Text { // Text is a child of the Rectangle above. anchors.verticalCenter: parent.verticalCenter horizontalAlignment: columnAligns[index] ...
If I make my array type variant, I get this error:
file:///home/mzimmers/git/KOL-UI/src/lib/qml/SortedTable.qml:234: TypeError: Cannot read property '3' of undefined
If I make my array type int, I don't get an error, but it doesn't work. Can someone explain what I'm doing wrong?
Thanks...

This stores the size of the array. So you're trying to use an
int
as anarray
so the QML engine chokes on it.property array columnAligns ...
should fix it.
Here's my favorite talk on that subject: https://www.destroyallsoftware.com/talks/wat
PS. Also JS is case sensitive.
aligncell0 != alignCell0

@kshegunov property array seems broken:
property int alignCell0: Text.AlignLeft property int alignCell1: Text.AlignRight property int alignCell2: Text.AlignLeft property int alignCell3: Text.AlignLeft property int alignCell4: Text.AlignLeft property int alignCell5: Text.AlignLeft property array columnAligns: [alignCell0, alignCell1, alignCell2, alignCell3, alignCell4, alignCell5]
Gives me:
file:///home/mzimmers/git/KOL-UI/src/lib/qml/SortedTable.qml:42 Expected property type
line 42 is the property array.
Thanks for catching my Case typos...

Yes, I'm a dum-dum. Just use
var
is what I meant to write, but failed miserably. -
Right you are (about var, not the dum-dum part). It works fine now. Thanks!
I also changed my variant (in the first example) to var, as I discovered today that variant is obsolete. FWIW...
