Detailed Description
A component that displays the waveform of a sample.
It uses a thumbnail data to display the waveform of the selected ModulatorSamplerSound and has some SampleArea objects that allow changing of its sample ranges (playback range, loop range etc.)
- See also
- SampleArea.
It uses a timer to display the current playbar.
Constructor & Destructor Documentation
| SamplerSoundWaveform | ( | const ModulatorSampler * | ownerSampler | ) |
Creates a new SamplerSoundWaveform.
- Parameters
-
ownerSampler the ModulatorSampler that the SamplerSoundWaveform should use.
Member Function Documentation
| void drawSampleStartBar | ( | Graphics & | g | ) |
draws a vertical ruler at the position where the sample was recently started.
| void setSoundToDisplay | ( | const ModulatorSamplerSound * | s, |
| int | multiMicIndex = 0 |
||
| ) |
Sets the currently displayed sound.
It listens for the global sound selection and displays the last selected sound if the selection changes.
|
override |
used to display the playing positions / sample start position.
| void toggleRangeEnabled | ( | AreaTypes | type | ) |
enables the range (makes it possible to drag the edges).
|
overridevirtual |
Call this whenever the sample ranges change.
If you only want to refresh the sample area (while dragging), use refreshSampleAreaBounds() instead.
