SVG Buttons

SvgButton Class

Located at magda/daw/ui/components/common/SvgButton.hpp in namespace magda.

Constructors

// Single icon — colors icon based on hover/press/active state
SvgButton(const juce::String& buttonName, const char* svgData, size_t svgDataSize);

// Dual icon — separate off/on SVGs with pre-baked colors
SvgButton(const juce::String& buttonName, const char* offSvgData, size_t offSvgDataSize,
          const char* onSvgData, size_t onSvgDataSize);

Usage Pattern

SvgButton requires constructor args, so use std::unique_ptr:

Header (include ui/components/common/SvgButton.hpp):

std::unique_ptr<magda::SvgButton> myButton_;

Constructor (BinaryData generated from CMakeLists):

myButton_ = std::make_unique<magda::SvgButton>("MyButton", BinaryData::icon_svg,
                                                BinaryData::icon_svgSize);
myButton_->setTooltip("Do something");
myButton_->onClick = [this] { /* handler */ };
addAndMakeVisible(myButton_.get());

resized() — use pointer dereference:

myButton_->setBounds(area.removeFromLeft(22));

Customization

// Colors (single-icon mode)
myButton_->setNormalColor(juce::Colour);
myButton_->setHoverColor(juce::Colour);
myButton_->setPressedColor(juce::Colour);
myButton_->setActiveColor(juce::Colour);

// Background colors
myButton_->setNormalBackgroundColor(juce::Colour);
myButton_->setActiveBackgroundColor(juce::Colour);

// Border
myButton_->setBorderColor(juce::Colour);
myButton_->setBorderThickness(float);

// Toggle state
myButton_->setActive(true);

Default colors come from DarkTheme: normal=TEXT_SECONDARY, hover=TEXT_PRIMARY, pressed/active=ACCENT_PRIMARY.

Adding an SVG to BinaryData

1. Place the SVG file in assets/icons/ (or a subdirectory)
2. Add it to the asset list in magda/daw/CMakeLists.txt:

   juce_add_binary_data(MagdaAssets SOURCES
       ...
       ../../assets/icons/my_icon.svg
       ...
   )
   

3. Rebuild — CMake generates BinaryData with the naming convention:
   • my_icon.svg → BinaryData::my_icon_svg / BinaryData::my_icon_svgSize
   • my-icon.svg → BinaryData::myicon_svg (hyphens stripped)
   • subdir/icon.svg → same as icon.svg (path not part of name)

Available Icon Locations

• assets/icons/ — app-specific icons (random.svg, enter.svg, delete.svg, etc.)
• assets/icons/fontaudio/ — FontAudio music icons (fad-*.svg)
• assets/icons/IO/ — input/output icons
• assets/icons/browser_icons/ — browser panel icons
• assets/icons/cloud_providers/ — cloud service logos

Dual-Icon Buttons (Toggle)

For buttons with distinct on/off visuals (e.g. play/pause):

myButton_ = std::make_unique<magda::SvgButton>(
    "PlayPause",
    BinaryData::play_off_svg, BinaryData::play_off_svgSize,
    BinaryData::play_on_svg, BinaryData::play_on_svgSize);
myButton_->setClickingTogglesState(true);

No need to set LookAndFeel — SvgButton has its own paintButton override.
