Detailed Description

Handles all Direct2D rendering in a CHistogramView.

Renders a histogram made up of single lines. Its size is fixed to 'width'. Also renders and repositions limit lines. Also can test for click hits on limit lines. All mutex protected.

Definition at line 16 of file D2HistogramRender.h.

Constructor & Destructor Documentation

d2d::D2HistogramRender::D2HistogramRender ( const D2HistogramRender &  )
protected

Disable copy.

d2d::D2HistogramRender::D2HistogramRender ( const uint32_t &  _width,
const uint32_t &  _channels,
scope::ScopeMultiHistogramPtr  _hist 
)

Initialize all to nullptr.

Definition at line 8 of file D2HistogramRender.cpp.

d2d::D2HistogramRender::~D2HistogramRender ( )

void d2d::D2HistogramRender::DiscardDeviceResources ( )
protected

Safely release all Direct2D resources.

Definition at line 25 of file D2HistogramRender.cpp.

D2HistogramRender d2d::D2HistogramRender::operator= ( const D2HistogramRender &  )
protected

Disable assignment.

void d2d::D2HistogramRender::Create ( const HWND &  _hwnd)

Creates the render target for a hwnd, the brushes for painting, and sets the limit position to the window edges.

Definition at line 31 of file D2HistogramRender.cpp.

void d2d::D2HistogramRender::SetHistogram ( scope::ScopeMultiHistogramPtr  _hist)

Sets the pointer to the current multi histogram.

Definition at line 49 of file D2HistogramRender.cpp.

void d2d::D2HistogramRender::Render ( )

Draws the current multi histogram with the limit lines.

Definition at line 54 of file D2HistogramRender.cpp.

void d2d::D2HistogramRender::Size ( const CSize &  size)

Resizes the renderer and the limit positions.

Definition at line 144 of file D2HistogramRender.cpp.

bool d2d::D2HistogramRender::ClickedAt ( const CPoint  _clickpoint,
uint32_t &  _channel,
bool &  _uplo 
)

Checks if click hit a limit (+-5 pixel) and if yes, on which channel and upper or lower limit line.

Parameters
[in]_clickpointthe point (in window coordinates) to test
[out]_channelhistogram of which channel was hit
[out]_uploif lower limit was hit false, if upper limit line was hit true
Returns
is the _clickpoint on (+-5 pixel) a limitline

void d2d::D2HistogramRender::SetLowerLimitPosition ( const uint32_t &  _channel,
const FLOAT &  _pos 
)

Set position of a lower limit line.

Definition at line 134 of file D2HistogramRender.cpp.

void d2d::D2HistogramRender::SetUpperLimitPosition ( const uint32_t &  _channel,
const FLOAT &  _pos 
)

Set position of an upper limit line.
