Surface3D 是 Qt Graphs QML 类型 3D 的一部分。Qt Graphs QML 类型 3D.

属性

axisX : ValueAxis3D
axisY : ValueAxis3D
axisZ : ValueAxis3D
flipHorizontalGrid : bool
selectedSeries : Surface3DSeries
seriesList : list<Surface3DSeries>

方法

void addSeries(Surface3DSeries series)
void removeSeries(Surface3DSeries series)

详细描述

此类型使开发者能够使用 Qt Quick 渲染 3D 表面图。

您需要导入 Qt Graphs 模块才能使用此类型。

import QtGraphs

之后，您可以在 qml 文件中使用 Surface3D。

import QtQuick
import QtGraphs
