Constructor & Destructor Documentation

◆ QQuickBorderImageMesh()

QQuickBorderImageMesh::QQuickBorderImageMesh ( QObject * parent = nullptr )

\qmltype BorderImageMesh \instantiates QQuickBorderImageMesh \inqmlmodule QtQuick

Since: 5.8

Defines a mesh with vertices arranged like those of a BorderImage.

BorderImageMesh provides BorderImage-like capabilities to a ShaderEffect without the need for a potentially costly ShaderEffectSource.

The following are functionally equivalent: \qml BorderImage { id: borderImage border { left: 10 right: 10 top: 10 bottom: 10 } source: "myImage.png" visible: false } ShaderEffectSource { id: effectSource sourceItem: borderImage visible: false } ShaderEffect { property var source: effectSource ... } \endqml

\qml Image { id: image source: "myImage.png" visible: false } ShaderEffect { property var source: image mesh: BorderImageMesh { border { left: 10 right: 10 top: 10 bottom: 10 } size: image.sourceSize } ... } \endqml

But the BorderImageMesh version can typically be better optimized.

Member Function Documentation

◆ border()

QQuickScaleGrid * QQuickBorderImageMesh::border ( ) const

\qmlpropertygroup QtQuick::BorderImageMesh::border
\qmlproperty int QtQuick::BorderImageMesh::border.left
\qmlproperty int QtQuick::BorderImageMesh::border.right
\qmlproperty int QtQuick::BorderImageMesh::border.top
\qmlproperty int QtQuick::BorderImageMesh::border.bottom

The 4 border lines (2 horizontal and 2 vertical) break the image into 9 sections,
as shown below:

\image declarative-scalegrid.png

Each border line (left, right, top, and bottom) specifies an offset in pixels
from the respective edge of the mesh. By default, each border line has
a value of 0.

For example, the following definition sets the bottom line 10 pixels up from
the bottom of the mesh:

\qml
BorderImageMesh {
    border.bottom: 10

... } \endqml

Definition at line 346 of file qquickshadereffectmesh.cpp.

◆ horizontalTileMode()

QQuickBorderImageMesh::TileMode QQuickBorderImageMesh::horizontalTileMode ( ) const

\qmlproperty enumeration QtQuick::BorderImageMesh::horizontalTileMode \qmlproperty enumeration QtQuick::BorderImageMesh::verticalTileMode

This property describes how to repeat or stretch the middle parts of an image.

\list

BorderImage.Stretch - Scales the image to fit to the available area.
BorderImage.Repeat - Tile the image until there is no more space. May crop the last image.
BorderImage.Round - Like Repeat, but scales the images down to ensure that the last image is not cropped. \endlist

The default tile mode for each property is BorderImage.Stretch.
