Make tst_qquickcanvasitem significant again; fix image size rounding

2020-03-05T04:52:14+00:00

- the test items must be visible, so that waitForRendering() works
- arcTo::test_paint tried to render an out-of-bounds arc, which
  resulted in rendering nothing.  Now renders within the 100x100 canvas.
- painted() is not emitted the first time the Canvas is rendered.
- Canvas.save() saves relative to the directory from which the test is
  run, while Canvas.loadImage() loads relative to the test data
  directory in this autotest (other tests are loading red.png for
  example).  So we need to use absolute paths to test loading and saving
  in the directory where the executable is.
- canvas.getContext('2d').getImageData(8.5, 8.5, 8.5, 8.5)
  now triggers different rounding behavior in QRectF::toRect(),
  after qtbase 88e56d0932a3615231adf40d5ae033e742d72c33:
  it becomes QRect(9,9 8x8).  The assert in qt_create_image_data()
  needs to accommodate that.
- Fixed another pedantic warning in qt_create_image_data a few
  lines above: if it creates the image itself, it needs to round
  the qreal width and height values.

The last four failures are due to high dpi issues.

Canvas: don't crash when getContext("2d") is called on destruction.

2015-01-26T16:28:37+00:00

We'd assume that a Window existed when that's not always the case.
For example:

import QtQuick 2.4
import QtQuick.Window 2.2
Window {
    Loader {
        sourceComponent: Canvas {
            Component.onDestruction: getContext("2d")
        }
        Component.onCompleted: active = false
    }
}

Canvas: do not emit paint when resized but hidden

2014-03-15T23:53:31+00:00

It turns out to be a bad idea (as in, breaks the enterprise controls)
to block paint() altogether when hidden. The original bug report
QTBUG-31830 only complained about paint() being emitted upon resize
while _hidden_, so this change solves exactly that. User is still
free to call requestPaint() even when hidden, and Canvas now doesn't
recklessly ignore the request.

Revert "Fix item polishing"

2014-02-27T23:02:38+00:00

This caused items like positioners and itemviews to not
relayout or update as appropriate when items were hidden,
and therefore caused problems all over in eg. controls.

Fix canvas tests after commit 439f31f128e70ecae16544ee7041695c60e0b2d6

2014-02-04T13:45:33+00:00

We must make sure that the canvas is created somewhere in the item hierarchy of
a scene-graph initialized (thus visible) window. A Window { visible: true }
type of item is not sufficient, but we can simply use our testcase as
parent/associated item, because that one is equipped with a when: windowShown
condition.
