Detailed Description

A base class for top-level windows that can be dragged around and resized.

To add content to the window, use its setContentOwned() or setContentNonOwned() methods to give it a component that will remain positioned inside it (leaving a gap around the edges for a border).

It's not advisable to add child components directly to a ResizableWindow: put them inside your content component instead. And overriding methods like resized(), moved(), etc is also not recommended - instead override these methods for your content component. (If for some obscure reason you do need to override these methods, always remember to call the super-class's resized() method too, otherwise it'll fail to lay out the window decorations correctly).

By default resizing isn't enabled - use the setResizable() method to enable it and to choose the style of resizing to use.

Member Enumeration Documentation

A set of colour IDs to use to change the colour of various aspects of the window.

These constants can be used either via the Component::setColour(), or LookAndFeel::setColour() methods.

See Also
Component::setColour, Component::findColour, LookAndFeel::setColour, LookAndFeel::findColour
Enumerator:
backgroundColourId 

A colour to use to fill the window's background.

Constructor & Destructor Documentation

ResizableWindow::ResizableWindow ( const String name,
bool  addToDesktop 
)

Creates a ResizableWindow.

This constructor doesn't specify a background colour, so the LookAndFeel's default background colour will be used.

Parameters
namethe name to give the component
addToDesktopif true, the window will be automatically added to the desktop; if false, you can use it as a child component
ResizableWindow::ResizableWindow ( const String name,
Colour  backgroundColour,
bool  addToDesktop 
)

Creates a ResizableWindow.

Parameters
namethe name to give the component
backgroundColourthe colour to use for filling the window's background.
addToDesktopif true, the window will be automatically added to the desktop; if false, you can use it as a child component
ResizableWindow::~ResizableWindow ( )

Destructor.

If a content component has been set with setContentOwned(), it will be deleted.

Member Function Documentation

Colour ResizableWindow::getBackgroundColour ( ) const
noexcept

Returns the colour currently being used for the window's background.

As a convenience the window will fill itself with this colour, but you can override the paint() method if you need more customised behaviour.

This method is the same as retrieving the colour for ResizableWindow::backgroundColourId.

See Also
setBackgroundColour
void ResizableWindow::setBackgroundColour ( Colour  newColour)

Changes the colour currently being used for the window's background.

As a convenience the window will fill itself with this colour, but you can override the paint() method if you need more customised behaviour.

Note that the opaque state of this window is altered by this call to reflect the opacity of the colour passed-in. On window systems which can't support semi-transparent windows this might cause problems, (though it's unlikely you'll be using this class as a base for a semi-transparent component anyway).

You can also use the ResizableWindow::backgroundColourId colour id to set this colour.

See Also
getBackgroundColour
void ResizableWindow::setResizable ( bool  shouldBeResizable,
bool  useBottomRightCornerResizer 
)

Make the window resizable or fixed.

Parameters
shouldBeResizablewhether it's resizable at all
useBottomRightCornerResizerif true, it'll add a ResizableCornerComponent at the bottom-right; if false, it'll use a ResizableBorderComponent around the edge
See Also
setResizeLimits, isResizable
bool ResizableWindow::isResizable ( ) const
noexcept

Returns true if resizing is enabled.

See Also
setResizable
void ResizableWindow::setResizeLimits ( int  newMinimumWidth,
int  newMinimumHeight,
int  newMaximumWidth,
int  newMaximumHeight 
)
noexcept

This sets the maximum and minimum sizes for the window.

If the window's current size is outside these limits, it will be resized to make sure it's within them.

A direct call to setBounds() will bypass any constraint checks, but when the window is dragged by the user or resized by other indirect means, the constrainer will limit the numbers involved.

See Also
setResizable, setFixedAspectRatio
ComponentBoundsConstrainer* ResizableWindow::getConstrainer ( )
noexcept

Returns the bounds constrainer object that this window is using.

You can access this to change its properties.

void ResizableWindow::setConstrainer ( ComponentBoundsConstrainer newConstrainer)

Sets the bounds-constrainer object to use for resizing and dragging this window.

A pointer to the object you pass in will be kept, but it won't be deleted by this object, so it's the caller's responsiblity to manage it.

If you pass a nullptr, then no contraints will be placed on the positioning of the window.

void ResizableWindow::setBoundsConstrained ( const Rectangle< int > &  bounds)

Calls the window's setBounds method, after first checking these bounds with the current constrainer.

bool ResizableWindow::isFullScreen ( ) const

Returns true if the window is currently in full-screen mode.

See Also
setFullScreen
void ResizableWindow::setFullScreen ( bool  shouldBeFullScreen)

Puts the window into full-screen mode, or restores it to its normal size.

If true, the window will become full-screen; if false, it will return to the last size it was before being made full-screen.

isFullScreen
bool ResizableWindow::isMinimised ( ) const

Returns true if the window is currently minimised.

See Also
setMinimised
void ResizableWindow::setMinimised ( bool  shouldMinimise)

Minimises the window, or restores it to its previous position and size.

When being un-minimised, it'll return to the last position and size it was in before being minimised.

isMinimised
bool ResizableWindow::isKioskMode ( ) const

Returns true if the window has been placed in kiosk-mode.

Desktop::setKioskComponent
String ResizableWindow::getWindowStateAsString ( )

Returns a string which encodes the window's current size and position.

This string will encapsulate the window's size, position, and whether it's in full-screen mode. It's intended for letting your application save and restore a window's position.

Use the restoreWindowStateFromString() to restore from a saved state.

See Also
restoreWindowStateFromString
bool ResizableWindow::restoreWindowStateFromString ( const String previousState)

Restores the window to a previously-saved size and position.

This restores the window's size, positon and full-screen status from an string that was previously created with the getWindowStateAsString() method.

Returns
false if the string wasn't a valid window state

getWindowStateAsString
Component* ResizableWindow::getContentComponent ( ) const
noexcept

Returns the current content component.

This will be the component set by setContentOwned() or setContentNonOwned, or nullptr if none has yet been specified.

See Also
setContentOwned, setContentNonOwned
void ResizableWindow::setContentOwned ( Component newContentComponent,
bool  resizeToFitWhenContentChangesSize 
)

Changes the current content component.

This sets a component that will be placed in the centre of the ResizableWindow, (leaving a space around the edge for the border).

You should never add components directly to a ResizableWindow (or any of its subclasses) with addChildComponent(). Instead, add them to the content component.

Parameters
newContentComponentthe new component to use - this component will be deleted when it's no longer needed (i.e. when the window is deleted or a new content component is set for it). To set a component that this window will not delete, call setContentNonOwned() instead.
resizeToFitWhenContentChangesSizeif true, then the ResizableWindow will maintain its size such that it always fits around the size of the content component. If false, the new content will be resized to fit the current space available.

Referenced by StandaloneFilterWindow::resetFilter(), and StandaloneFilterWindow::StandaloneFilterWindow().

void ResizableWindow::setContentNonOwned ( Component newContentComponent,
bool  resizeToFitWhenContentChangesSize 
)

Changes the current content component.

This sets a component that will be placed in the centre of the ResizableWindow, (leaving a space around the edge for the border).

You should never add components directly to a ResizableWindow (or any of its subclasses) with addChildComponent(). Instead, add them to the content component.

Parameters
newContentComponentthe new component to use - this component will NOT be deleted by this component, so it's the caller's responsibility to manage its lifetime (it's ok to delete it while this window is still using it). To set a content component that the window will delete, call setContentOwned() instead.
resizeToFitWhenContentChangesSizeif true, then the ResizableWindow will maintain its size such that it always fits around the size of the content component. If false, the new content will be resized to fit the current space available.
void ResizableWindow::clearContentComponent ( )

Removes the current content component.

If the previous content component was added with setContentOwned(), it will also be deleted. If it was added with setContentNonOwned(), it will simply be removed from this component.

void ResizableWindow::setContentComponentSize ( int  width,
int  height 
)

Changes the window so that the content component ends up with the specified size.

This is basically a setSize call on the window, but which adds on the borders, so you can specify the content component's target size.

virtual BorderSize<int> ResizableWindow::getBorderThickness ( )
virtual

Returns the width of the frame to use around the window.

getContentComponentBorder
virtual BorderSize<int> ResizableWindow::getContentComponentBorder ( )
virtual

Returns the insets to use when positioning the content component.
