BackgroundGrid Class | ArcGIS Maps SDK for Qt

Defines the default color and context grid for display behind a map or scene surface. More...

Member Function Documentation BackgroundGrid::BackgroundGrid()

Constructs a default BackgroundGrid.

These default values are used: l color = Qt::black, l gridLineColor = c Qt::white, l gridLineWidth = 1, l gridSize = 32.

BackgroundGrid::BackgroundGrid(const QColor &color, const QColor &gridLineColor, float gridLineWidth, float gridSize)

Creates a BackgroundGrid with the specified color, gridLineColor, gridLineWidth and gridSize.

BackgroundGrid is the grid that displays behind a Map in a MapView, or a Surface in a SceneView. If there is no map or surface provided, an empty view will display with only the BackgroundGrid.

An instance of this class can be used to set a default backdrop that a Map or Scene will display on top of.

Note that gridLineWidth and gridSize are defined in device-independent pixels.

color - The color of the background.
gridLineColor - The color of the grid lines.
gridLineWidth - The width of the grid lines in device-independent pixels (DIP).
gridSize - The size of the grid squares in device-independent pixels (DIP).

BackgroundGrid::BackgroundGrid(const Esri::ArcGISRuntime::BackgroundGrid &other)

Copy constructor from other BackgroundGrid.

[noexcept] BackgroundGrid::BackgroundGrid(Esri::ArcGISRuntime::BackgroundGrid &&other)

Move constructor from other BackgroundGrid.

[noexcept] BackgroundGrid::~BackgroundGrid()

Destructor.

QColor BackgroundGrid::color() const

Returns the fill color of the background.

The default value is Silver ("#C0C0C0" or QColor(192, 192, 192)).

See also setColor().

QColor BackgroundGrid::gridLineColor() const

Returns the color of the background grid lines.

The default value is Black ("#FFFFFF" or QColor(255, 255, 255)).

See also setGridLineColor().

double BackgroundGrid::gridLineWidth() const

Returns the width of the grid lines in device-independent pixels (DIP).

This value must be greater than or equal to 0. Setting the grid line width to 0 will make grid lines invisible. The default value is 0.1.

See also setGridLineWidth().

double BackgroundGrid::gridSize() const

Returns the size of each grid square in device-independent pixels (DIP).

The default value is 20 x 20 pixels.

See also setGridSize().

[since Esri::ArcGISRuntime 100.3] bool BackgroundGrid::isVisible() const

Returns true if grid lines are visible on the color, false otherwise.

In the context of MapView, this value indicates if the gridLineColor is visible. In the context of SceneView, this value indicates if both the color and the gridLineColor are visible.

The default value is true.

This function was introduced in Esri::ArcGISRuntime 100.3.

void BackgroundGrid::setColor(const QColor &color)

Sets the fill color of the background.

The default value is Silver ("#C0C0C0" or QColor(192, 192, 192)).

See also color().

void BackgroundGrid::setGridLineColor(const QColor &color)

Sets the color of the background grid lines.

The default value is Black ("#FFFFFF" or QColor(255, 255, 255)).

See also gridLineColor().

void BackgroundGrid::setGridLineWidth(double gridLineWidth)

Sets the width of the background grid lines to gridLineWidth DIPs.

The default value is 1. This value must be greater than or equal to 0. Setting the grid line width to 0 will make grid lines invisible.

See also gridLineWidth().

void BackgroundGrid::setGridSize(double gridSize)

Sets the size of the background grid to gridSize DIPs.

The default value is 20.0.

See also gridSize().

[since Esri::ArcGISRuntime 100.3] void BackgroundGrid::setVisible(bool visible)

Sets whether the grid lines are visible in the background to visible.

If this value is true, grid lines will display on top of the BackgroundGrid::Color. If this value false, the BackgroundGrid::Color will display without the grid lines. The default value is true.

This function was introduced in Esri::ArcGISRuntime 100.3.

See also isVisible().

[since Esri::ArcGISRuntime 200.6] bool BackgroundGrid::operator!=(const Esri::ArcGISRuntime::BackgroundGrid &other) const

Returns true if this object is not equal to a second BackgroundGrid object.

other - The second object.

This function was introduced in Esri::ArcGISRuntime 200.6.

[noexcept] Esri::ArcGISRuntime::BackgroundGrid &BackgroundGrid::operator=(Esri::ArcGISRuntime::BackgroundGrid &&other)

Move operator from other BackgroundGrid.

Esri::ArcGISRuntime::BackgroundGrid &BackgroundGrid::operator=(const Esri::ArcGISRuntime::BackgroundGrid &other)

Assignment operator from other BackgroundGrid.

[since Esri::ArcGISRuntime 200.6] bool BackgroundGrid::operator==(const Esri::ArcGISRuntime::BackgroundGrid &other) const

Returns true if this object is equal to a second BackgroundGrid object.

other - The second object.

This function was introduced in Esri::ArcGISRuntime 200.6.
