Detailed Description

GUIApplication, the frame, GUIContent and event handlers.

Derive from tachyon::GUIApplication and describe the UI in OnGUI(); every control is one of its member functions. The class page groups them by family. The Overview explains the frame model, and Controls covers each control.

◆ IsActivationKey()

bool tachyon::IsActivationKey ( const ElementEvent & event )

inline

#include <gui_controls/gui_default_handlers.h>

True for a KeyDown of Return, keypad Enter or Space.

◆ TextEditorUsesKey()

bool tachyon::TextEditorUsesKey	(	const InputState &	state,
		bool	readOnly )

#include <gui_controls/gui_default_handlers.h>

Whether a focused text editor acts on this key (KeyDown/KeyUp), so its handler takes it; the rest reach the app's shortcuts.

Read-only text only selects and copies.

◆ MakeTextBoxHandler()

EventHandler tachyon::MakeTextBoxHandler ( GUIStateManager & guiStateManager )

#include <gui_controls/gui_default_handlers.h>

Text box handler: a left click focuses it for editing; while focused it takes text input and the keys its editor uses.

◆ MakeHorizontalSizerHandler()

		const ElementStorage &	elementStorage,
		int &	sizeValue,
		int	minSize,
		int	maxSize,

		std::function< int()>	onAutoSize = nullptr,
		bool	invertMouseDelta = false,
		float	pixelsPerUnit = 1.0f )

#include <gui_controls/gui_default_handlers.h>

Sizer handler that drags sizeValue within [minSize, maxSize], calling onChanged with each new size.

Sizes are in units of pixelsPerUnit pixels of the sizer's layout (for CSS px pass StyleManager::GetUIScale()). onAutoSize runs on double-click and returns the desired size in pixels, or -1 to skip. invertMouseDelta grows the size when dragging left. Escape during the drag puts the size back.

◆ MakeVerticalSizerHandler()

EventHandler tachyon::MakeVerticalSizerHandler	(	GUIStateManager &	guiStateManager,
		const ElementStorage &	elementStorage,
		int &	sizeValue,
		int	minSize,
		int	maxSize,
		std::function< void(int)>	onChanged = nullptr,
		std::function< int()>	onAutoSize = nullptr,
		bool	invertMouseDelta = false,
		float	pixelsPerUnit = 1.0f )

#include <gui_controls/gui_default_handlers.h>

Y-axis counterpart of MakeHorizontalSizerHandler; invertMouseDelta grows the size when dragging up.

◆ MakeSliderHandler()

EventHandler tachyon::MakeSliderHandler	(	GUIStateManager &	guiStateManager,
		const ElementStorage &	elementStorage,
		float *	value,
		int	elementWidth,
		std::function< void()>	onChanged = nullptr,
		float	minVal = 0.0f,
		float	maxVal = 1.0f,
		SliderPress	press = SliderPress::Edit )

#include <gui_controls/gui_default_handlers.h>

Slider handler for *value in [minVal, maxVal]; elementWidth (pixels, <= 0 is treated as 1) maps drag distance onto that range.

Arrow keys step 1% of the range, PageUp/Down 10%.

◆ MakeDraggableLabelHandler()

EventHandler tachyon::MakeDraggableLabelHandler	(	GUIStateManager &	guiStateManager,
		const ElementStorage &	elementStorage )

#include <gui_controls/gui_default_handlers.h>

Turns mouse drags on a label into LabelDrag* events sent to the next sibling element.

A press released without dragging focuses that control; Escape during a drag cancels it.

◆ MakeLabelHandler()

EventHandler tachyon::MakeLabelHandler	(	GUIStateManager &	guiStateManager,
		const ElementStorage &	elementStorage )

#include <gui_controls/gui_default_handlers.h>

Label handler: a left click focuses the control bound to the label (else the label).

◆ MakeGroupLabelHandler()

EventHandler tachyon::MakeGroupLabelHandler	(	GUIStateManager &	guiStateManager,
		const ElementStorage &	elementStorage,
		LabelGroupVisualState	groupVisual )

#include <gui_controls/gui_default_handlers.h>

Label group variants: the right edge resizes the shared label width.

◆ MakeGroupDraggableLabelHandler()

EventHandler tachyon::MakeGroupDraggableLabelHandler	(	GUIStateManager &	guiStateManager,

◆ MakeButtonHandler()

EventHandler tachyon::MakeButtonHandler	(	GUIStateManager &	guiStateManager,
		std::function< void()>	onClick )

#include <gui_controls/gui_default_handlers.h>

Button handler: a left click, or an activation key while focused, calls onClick.

◆ MakeMouseWheelScrollHandler()

EventHandler tachyon::MakeMouseWheelScrollHandler	(	ScrollManagement &	scrollManagement,
		float	wheelStep )

#include <gui_controls/gui_default_handlers.h>

Wheel handler that scrolls the element's own scroll offset by wheelStep pixels per notch (StyleManager::Px(kWheelScrollStep)).

◆ MakeScrollbarHandler()

EventHandler tachyon::MakeScrollbarHandler	(	GUIStateManager &	guiStateManager,
		ElementStorage &	elementStorage,
		ID	containerID,
		bool	vertical,
		int32_t	trackLength = 0 )

#include <gui_controls/gui_default_handlers.h>

Scrollbar track/thumb handler; writes the scroll offset of containerID (the scrollable parent).

Escape during a drag puts the scroll position back. trackLength = 0: span-and-clip, the bar spans kScrollbarAxisSpan and the track is the parent's innerRect. trackLength > 0: the bar is sized explicitly (to leave room for a corner cap, say) and the track is its own rect.

◆ MakeDragSourceHandler()

EventHandler tachyon::MakeDragSourceHandler	(	GUIStateManager &	guiStateManager,
		uint32_t	payloadType,
		std::function< uintptr_t()>	getPayloadValue = nullptr,
		std::function< std::any()>	getPayload = nullptr,
		DragVisualizer	sourceVisualizer = {} )

#include <gui_controls/gui_default_handlers.h>

Drag source handler: a left press starts a drag of payloadType, with the value from getPayloadValue (else 0) and the payload from getPayload (else that value).

◆ MakeDropTargetHandler()

EventHandler tachyon::MakeDropTargetHandler	(	uint32_t	acceptedPayloadType,
		std::function< void(uintptr_t payloadValue, ID sourceID)>	onDrop,
		std::function< bool(uintptr_t payloadValue)>	canDrop = nullptr )

#include <gui_controls/gui_default_handlers.h>

Drop target handler for acceptedPayloadType; onDrop gets the payload value and the source ID.

canDrop (optional) returning false makes the element a non-target for that payload.

◆ LabelDragSpeedScale()

double tachyon::LabelDragSpeedScale ( const InputState & state )

inline

#include <gui_controls/gui_default_handlers.h>

Label-drag speed multiplier: 0.1 with Ctrl, 10 with Shift (which wins), else 1.

◆ ReportingChanges()

template<typename T>

EventHandler tachyon::ReportingChanges	(	GUIStateManager &	guiStateManager,
		T *	value,
		EventHandler	inner )

inline

#include <gui_controls/gui_default_handlers.h>

Wraps a handler that writes *value: it runs during input, after the control's call returned, so a change marks the element clicked and the next call reports it (Interaction().HasBeenClicked(id)).

◆ MakeNumericalBoxHandler()

template<typename T>

EventHandler tachyon::MakeNumericalBoxHandler	(	GUIStateManager &	guiStateManager,
		T &	value,
		NumericFieldConfig< T >	config = {} )

inline

#include <gui_controls/gui_default_handlers.h>

Numeric field handler: a left click focuses it for typing, and LabelDrag* events from its label drag value (a cancelled drag restores the start value).

◆ MakeMultiDimDragHandler()

template<typename T>

EventHandler tachyon::MakeMultiDimDragHandler	(	GUIStateManager &	guiStateManager,
		T &	value,
		NumericFieldConfig< typename TypeDimensions< T >::ComponentType >	config = {} )

		ElementState	state )

#include <gui_controls/gui_transition_manager.h>

Flat GPU style index for a base pool index and state.

Must match vk_renderer.cpp and StyleManager::GetVisualBoxStyle (VisualMask, Disabled collapsing).

Variable Documentation

◆ kScrollbarMinThumbLength

int32_t tachyon::kScrollbarMinThumbLength = 20

constexpr

#include <gui_controls/gui_default_handlers.h>

Minimum thumb length in CSS pixels (scale with StyleManager::Px), so the thumb stays clickable over huge content.

The thickness is GUITheme::scrollbarThickness.
