Detailed Description

template<typename TView>
class pongasoft::VST::GUI::Views::CustomViewAdapter< TView >

This class can be used to extend VSTGUI classes directly while still benefiting from the extensions added by Jamba.

CustomView extends CView to create a completely custom class. If, on the other end, you simply want to extend another class from VSTGUI (ex: CTextEdit), you can use this class which implements most of the behavior from CustomView.

In addition to the attributes exposed by TView, this class exposes the following attributes:

Attribute Description

custom-view-tag

The tag associated to this custom view. This tag (which is not related to a parameter), is optional and can be used to differentiate between views when implementing a custom controller.

// Example
CView *SampleEditController::verifyView(CView *iView,
                                        const UIAttributes &iAttributes,
                                        const IUIDescription *iDescription)
{
  auto button = dynamic_cast<Views::TextButtonView *>(iView);
  if(button) {
    switch(button->getCustomViewTag()) {
      case ESampleSplitterParamID::kNormalize0Action:
        initButton(button, SampleDataAction::Type::kNormalize0, false);
        break;
        // ....
     }
  }
}

editor-mode

A flag whose purpose is to render/log information during development when the flag is set to true. It can be flipped directly in the VSTGUI Editor without having to recompile the code.

// Example
void SampleEditView::draw(CDrawContext *iContext) {
// ...
#if EDITOR_MODE
 if(getEditorMode())
 {
   auto rdc = pongasoft::VST::GUI::RelativeDrawContext{this, iContext};
   rdc.debug("SampleRange: [%.3f,%.3f] | PixelRange: [%.3f,%.3f] | Visible: [%.3f,%.3f] | BPM: %f",
             fState->fWESelectedSampleRange->fFrom, fState->fWESelectedSampleRange->fTo,
             fSelectedPixelRange.fFrom, fSelectedPixelRange.fTo,
             fVisibleSampleRange.fFrom, fVisibleSampleRange.fTo,
             fHostInfo->fTempo);
 }
#endif
}

Note: Since getEditorMode() always returns false in release build mode, it is recommended to enclose such code in an #if / #endif block as shown in the example.

Template Parameters

TView the view class (for ex: CTextEdit)

Member Function Documentation

◆ afterApplyAttributes()

void afterApplyAttributes ( )

inlineoverridevirtual

Handles the lifecycle behavior getting triggered once all the attributes have been set (which usually happens after the XML file (uidesc) has been read/processed, or when you modify attributes in the VSTGUI Editor).

Note: Subclasses are allowed to extend this behavior (if you want to do some extra setup when the view is initialized for example), but care should be taken in making sure that this method ends up being called, otherwise the view will most likely not behave as expected.

Reimplemented from ICustomViewLifecycle.

◆ getCustomViewTag()

TagID getCustomViewTag ( ) const

inline

The tag associated to this custom view.

This tag (which is not related to a parameter), is optional and can be used to differentiate between views when implementing a custom controller.

// Example
CView *SampleEditController::verifyView(CView *iView,
                                        const UIAttributes &iAttributes,
                                        const IUIDescription *iDescription)
{
  auto button = dynamic_cast<Views::TextButtonView *>(iView);
  if(button) {
    switch(button->getCustomViewTag()) {
      case ESampleSplitterParamID::kNormalize0Action:
        initButton(button, SampleDataAction::Type::kNormalize0, false);
        break;
        // ....
     }
  }
}

◆ getEditorMode()

bool getEditorMode ( ) const

inline

A flag whose purpose is to render/log information during development when the flag is set to true.

It can be flipped directly in the VSTGUI Editor without having to recompile the code.

// Example
void SampleEditView::draw(CDrawContext *iContext) {
// ...
#if EDITOR_MODE
 if(getEditorMode())
 {
   auto rdc = pongasoft::VST::GUI::RelativeDrawContext{this, iContext};
   rdc.debug("SampleRange: [%.3f,%.3f] | PixelRange: [%.3f,%.3f] | Visible: [%.3f,%.3f] | BPM: %f",
             fState->fWESelectedSampleRange->fFrom, fState->fWESelectedSampleRange->fTo,
             fSelectedPixelRange.fFrom, fSelectedPixelRange.fTo,
             fVisibleSampleRange.fFrom, fVisibleSampleRange.fTo,
             fHostInfo->fTempo);
 }
#endif
}

Note: Since getEditorMode() always returns false in release build mode, it is recommended to enclose such code in an #if / #endif block as shown in the example.

◆ markDirty()

void markDirty ( )

inline

Marks this view dirty which will (at the appropriate time in the rendering lifecycle) trigger a call to draw()

Warning: You should not call draw() yourself but instead call this method which will invoke draw() at the appropriate time (for example, calling markDirty() 3 times will not invoke draw() 3 times...).

◆ onParameterChange()

void onParameterChange ( ParamID iParamID )

inlineoverridevirtual

Callback when a parameter changes.

By default simply marks the view as dirty. This method is intended to be overriden to implement specific behavior.

Reimplemented from ParamAware.

◆ setCustomViewTag()

void setCustomViewTag ( TagID iTag )

inline

See also: getCustomViewTag()

◆ setEditorMode()

void setEditorMode ( bool iEditorMode )

inline

See also: getEditorMode()
