Detailed Description
A component that resizes its parent component when dragged.
This component forms a bar along one edge of a component, allowing it to be dragged by that edges to resize it.
To use it, just add it to your component, positioning it along the appropriate edge. Make sure you reposition the resizer component each time the parent's size changes, to keep it in the correct position.

Constructor & Destructor Documentation
◆ ResizableEdgeComponent()
| juce::ResizableEdgeComponent::ResizableEdgeComponent | ( | Component * | componentToResize, |
| ComponentBoundsConstrainer * | constrainer, | ||
| Edge | edgeToResize ) |
Creates a resizer bar.
Pass in the target component which you want to be resized when this one is dragged. The target component will usually be this component's parent, but this isn't mandatory.
Remember that when the target component is resized, it'll need to move and resize this component to keep it in place, as this won't happen automatically.
If the constrainer parameter is not a nullptr, then this object will be used to enforce limits on the size and position that the component can be stretched to. Make sure that the constrainer isn't deleted while still in use by this object.

Member Function Documentation
◆ isVertical()

noexcept |
◆ mouseDown()
|
overrideprotectedvirtual |
Called when a mouse button is pressed.
The MouseEvent object passed in contains lots of methods for finding out which button was pressed, as well as which modifier keys (e.g. shift, ctrl) were held down at the time.
Once a button is held down, the mouseDrag method will be called when the mouse moves, until the button is released.
- Parameters
-
Event details about the position and status of the mouse event, including the source component in which it occurred
- See also
- mouseUp, mouseDrag, mouseDoubleClick, contains
Reimplemented from juce::Component.
◆ mouseDrag()
|
overrideprotectedvirtual |
Called when the mouse is moved while a button is held down.
When a mouse button is pressed inside a component, that component receives mouseDrag callbacks each time the mouse moves, even if the mouse strays outside the component's bounds.
- Parameters
-
Event details about the position and status of the mouse event, including the source component in which it occurred
- See also
- mouseDown, mouseUp, mouseMove, contains, setDragRepeatInterval
Reimplemented from juce::Component.
◆ mouseUp()
|
overrideprotectedvirtual |
Called when a mouse button is released.
A mouseUp callback is sent to the component in which a button was pressed even if the mouse is actually over a different component when the button is released.
The MouseEvent object passed in contains lots of methods for finding out which buttons were down just before they were released.
- Parameters
-
Event details about the position and status of the mouse event, including the source component in which it occurred
- See also
- mouseDown, mouseDrag, mouseDoubleClick, contains
Reimplemented from juce::Component.
◆ paint()
Components can override this method to draw their content.
The paint() method gets called when a region of a component needs redrawing, either because the component's repaint() method has been called, or because something has happened on the screen that means a section of a window needs to be redrawn.
Any child components will draw themselves over whatever this method draws. If you need to paint over the top of your child components, you can also implement the paintOverChildren() method to do this.
If you want to cause a component to redraw itself, this is done asynchronously - calling the repaint() method marks a region of the component as "dirty", and the paint() method will automatically be called sometime later, by the message thread, to paint any bits that need refreshing. In JUCE (and almost all modern UI frameworks), you never redraw something synchronously.
You should never need to call this method directly - to take a snapshot of the component you could use createComponentSnapshot() or paintEntireComponent().
- Parameters
-
g the graphics context that must be used to do the drawing operations.
