Graphs3D QML Type

Graphs3D namespace enums. More...

Import Statement: import QtGraphs

List of all members, including inherited members
Graphs3D is part of Qt Graphs QML Types for 3D.

Detailed Description

The Graphs3D namespace provides the following enums used by QtGraphs' 3D API.

Graphs3D.SelectionFlag

Item selection modes. Values of this enumeration can be combined with OR operator.

Constant	Description
`None`	Selection mode disabled.
`Item`	Selection highlights a single item.
`Row`	Selection highlights a single row.
`ItemAndRow`	Combination flag for highlighting both item and row with different colors.
`Column`	Selection highlights a single column.
`ItemAndColumn`	Combination flag for highlighting both item and column with different colors.
`RowAndColumn`	Combination flag for highlighting both row and column.
`ItemRowAndColumn`	Combination flag for highlighting item, row, and column.
`Slice`	Setting this mode flag indicates that the graph should take care of the slice view handling automatically. If you wish to control the slice view yourself via Q3DScene, do not set this flag. When setting this mode flag, either `Row` or `Column` must also be set, but not both. Slicing is supported by Bars3D and Surface3D only. When this flag is set, slice mode is entered in the following situations: When selection is changed explicitly via series API to a visible item When selection is changed by clicking on the graph When the selection mode changes and the selected item is visible
`MultiSeries`	Setting this mode means that items for all series at same position are highlighted, instead of just the selected item. The actual selection in the other series doesn't change. When setting this mode flag, one or more of the basic selection flags (`Item`, `Row`, or `Column`) must also be set. Multi-series selection is not supported for Scatter3D.

Graphs3D.ShadowQuality

Quality and softness of shadows.

Constant	Description
`None`	Shadows are disabled.
`Low`	Shadows are rendered in low quality.
`Medium`	Shadows are rendered in medium quality.
`High`	Shadows are rendered in high quality.
`SoftLow`	Shadows are rendered in low quality with softened edges.
`SoftMedium`	Shadows are rendered in medium quality with softened edges.
`SoftHigh`	Shadows are rendered in high quality with softened edges.

Graphs3D.ElementType

Type of an element in the graph.

Constant	Description
`None`	No defined element.
`Series`	An item in a series.
`AxisXLabel`	The x-axis label.
`AxisYLabel`	The y-axis label.
`AxisZLabel`	The z-axis label.
`CustomItem`	A custom item.

Graphs3D.OptimizationHint

The optimization hint for rendering.

Constant	Description
`Default`	Provides the full feature set with instancing at a good performance.
`Legacy`	Provides the full feature set at a reasonable performance. To be used if OptimizationHint.Default performs poorly or does not work.

Graphs3D.CameraPreset

Predefined positions for camera.

Constant	Description
`NoPreset`	Used to indicate a preset has not been set, or the scene has been rotated freely.
`FrontLow`	Both x and y rotations of the camera are 0.
`Front`	X rotation is 0 and y rotation is 22.5 degrees.
`FrontHigh`	X rotation is 0 and y rotation is 45 degrees.
`LeftLow`	X rotation is 90 and y rotation is 0 degrees.
`Left`	X rotation is 90 and y rotation is 22.5 degrees.
`LeftHigh`	X rotation is 90 and y rotation is 45 degrees.
`RightLow`	X rotation is -90 and y rotation is 0 degrees.
`Right`	X rotation is -90 and y rotation is 22.5 degrees.
`RightHigh`	X rotation is -90 and y rotation is 45 degrees.
`BehindLow`	X rotation is 180 and y rotation is 0 degrees.
`Behind`	X rotation is 180 and y rotation is 22.5 degrees.
`BehindHigh`	X rotation is 180 and y rotation is 45 degrees.
`IsometricLeft`	X rotation is 45 and y rotation is 22.5 degrees.
`IsometricLeftHigh`	X rotation is 45 and y rotation is 45 degrees.
`IsometricRight`	X rotation is -45 and y rotation is 22.5 degrees.
`IsometricRightHigh`	X rotation is -45 and y rotation is 45 degrees.
`DirectlyAbove`	X rotation is 0 and y rotation is 90 degrees.
`DirectlyAboveCW45`	X rotation is -45 and y rotation is 90 degrees.
`DirectlyAboveCCW45`	X rotation is 45 and y rotation is 90 degrees.
`FrontBelow`	X rotation is 0 and y rotation is -45 degrees. In Bars3D from FrontBelow onward these only work for graphs including negative values. They act as CameraPreset...Low for positive-only values.
`LeftBelow`	X rotation is 90 and y rotation is -45 degrees.
`RightBelow`	X rotation is -90 and y rotation is -45 degrees.
`BehindBelow`	X rotation is 180 and y rotation is -45 degrees.
`DirectlyBelow`	X rotation is 0 and y rotation is -90 degrees. Acts as FrontLow for positive-only bars.

Graphs3D.GridLineType

Constant	Description
`Shader`	Grid lines are rendered with GPU in a shader.
`Geometry`	Grid lines are rendered with 3D models.

Graphs3D.RenderingMode

Constant Description

DirectToBackground Indicates that the graph will be rendered directly on the window background and QML items are rendered on top of it. Using non-transparent QML item as a background will hide the graph. Clears the whole window before rendering the graph, including the areas outside the graph. If the surface format of the window supports antialiasing, it will be used (see qDefaultSurfaceFormat()). This rendering mode offers the best performance at the expense of non-standard QML behavior. For example, the graphs do not obey the z ordering of QML items and the opacity value has no effect on them.

Indirect Indicates the graph will be first rendered to an offscreen surface that is then drawn during normal QML item rendering. The rendered image is antialiased using the multisampling method if it is supported in the current environment and the msaaSamples property value is greater than zero. This rendering mode offers good quality and normal QML item behavior at the expense of performance.
