Detailed Description

Gadget-related class.

Library: ilvadvgdt

IlvNotebookPage is the implementation of the page of a notebook (see the class IlvNotebook).


- IlvNotebook and IlvNotebookPage -


The notebook page is composed of a rectangular usable area and a tab that can contain a label, a bitmap or both. The class IlvNotebookPage creates an IlvGadgetContainer to display the contents of the page.

See also
IlvNotebook.

Member Function Documentation

◆ createView()

virtual IlvView* IlvNotebookPage::createView ( IlvAbstractView parent,
const IlvRect rect 
)
virtual

Is called to create the view associated with the page.

Creates the view associated with the page. You can overload this method to create any kind of view. This method also reads the .ilv file. The default implementation creates and returns an IlvGadgetContainer.

Parameters
parentThe parent view of the created view.
rectThe size and position of the created view.
See also
deleteView().

◆ deleteView()

virtual void IlvNotebookPage::deleteView ( )
virtual

Is called when the view associated with the page is deleted.

See also
createView().

◆ deSelect()

virtual void IlvNotebookPage::deSelect ( )
virtual

Is called by the notebook when the page is deselected.

Is called by the IlvNotebook::pageDeselected() method when the page is deselected. The default implementation hides the view associated with this page.

See also
IlvNotebook::pageDeselected(), select().

◆ draw()

virtual void IlvNotebookPage::draw ( IlvPort dst,
const IlvRect pageRect,
const IlvTransformer t,
const IlvRegion clip 
) const
virtual

Called by the notebook to draw the contents of the page.

If the page has no associated view, the method tries to create the view by calling the IlvNotebook::createView() method. You can overload this method to do your own drawing.

Parameters
dstThe drawing destination port.
pageRectThe rectangle of the page, with the margin defined in the notebook taken into account.
tThe transformer through which the notebook is drawn.
clipThe clipping area.
See also
drawTab().

◆ drawTab()

virtual void IlvNotebookPage::drawTab ( IlvPort dst,
const IlvRect rect,
const IlvRegion clip 
) const
virtual

Draws the content of the tab.

Draws the content of the tab. You can overload this method to draw whatever you need.

Parameters
dstThe drawing destination port.
rectThe bounding box of the tab.
clipThe clipping area.
See also
draw().

◆ getBitmap()

const char* IlvNotebookPage::getName ( ) const
virtual

Returns the page name.

Returns
The page name or 0 if there is none. Do not modify or delete the returned string.
See also
setName(), IlvNotebook::getPage(const char*).

Reimplemented from IlvValueInterface.

◆ getNamedProperty()

IlvNamedProperty* IlvNotebookPage::getNamedProperty ( const IlSymbol name) const

Returns a named property of the object.

Parameters
nameThe property name.
Returns
A pointer to the named property object associated with the current object having the name name. Returns null if no named property matches the name name.

◆ getProperty()

IlAny IlvNotebookPage::getProperty ( const IlSymbol key) const

Returns a given property of the object.

Parameters

virtual void IlvNotebookPage::getTabSize ( IlvDim width,
IlvDim height 
) const
virtual

Computes the size of the tab.

Overload this method to change the size of the tab.

Parameters
widthThe width of the tab.
heightThe height of the tab.

◆ getView()

virtual IlvView* IlvNotebookPage::getView ( )
virtual

Returns the view associated with the page.

If no such view exists, the method creates the views by calling the IlvNotebook::createView() method.

Returns
The view associated with the page.
See also
IlvNotebook::createView(), IlvNotebookPage::createView().

◆ getViewAsContainer()

virtual IlvContainer* IlvNotebookPage::getViewAsContainer ( )
virtual

Returns the view associated with the page as an IlvContainer.

If the View exists, but is not an IlvContainer, this returns a nullptr. If no such view exists, the method creates the views by calling the IlvNotebook::createView() method.

Returns
The IlvContainer associated with the page.
See also
IlvNotebook::createView(), IlvNotebookPage::createView().

◆ hasProperty()

IlBoolean IlvNotebookPage::hasProperty ( const IlSymbol key) const

Checks that the object has a given property.

Parameters
keyThe symbol that specifies the property.
Returns
IlTrue if the key property was found, or IlFalse if the key property was not found.
See also
setProperty(), removeProperty(), getProperty().

◆ isSensitive()

IlBoolean IlvNotebookPage::isSensitive ( ) const

Returns a Boolean indicating the page sensitivity.

Returns
IlTrue if the page is sensitive, that is, it can be selected.
See also
setSensitive().

◆ read()

static IlvNotebookPage* IlvNotebookPage::read ( IlvInputFile file,
IlvNotebook notebook 
)
static

Reads an object description from a file.

Reads an object description from the file input. It reads the information that was saved by the member function write() to be able to create a new instance of this object. Usually, because of the availability of the constructor that expects an IlvInputFile, readItem() should be equivalent to:

MyClass::read(IlvInputFile& file, IlvNotebook* notebook)
{
return new MyClass(file, notebook);
}
Parameters
fileThe file to be read from.
notebookThe notebook that contains the page.
See also
DeclareNotebookPageInfoRO(), DeclareNotebookPageInfo(), IlvPredefinedNotebookPageIOMembers().
Note
The read() method is not capitalized like other static methods so that it is consistent with the write() method.

◆ removeNamedProperty()

IlvNamedProperty* IlvNotebookPage::removeNamedProperty ( IlSymbol name)

Removes a named property from the object.

Parameters
nameThe property name.
Returns
The named property that was previously associated with this object having the same name, so that you can delete it or keep it for further handling. If no previous named property was associated with this object having the name property, this function returns 0.
See also
getNamedProperty(), setNamedProperty().

◆ removeProperty()

IlBoolean IlvNotebookPage::removeProperty ( const IlSymbol key)

Removes a property of the object.

Parameters
keyThe symbol that specifies the property.
Returns
IlTrue if the key property was found, or IlFalse if the key property was not found.
See also
setProperty(), getProperty(), hasProperty().

◆ resized()

virtual void IlvNotebookPage::resized ( )
virtual

Is called when the page is resized.

The default implementation resizes the view associated with this page.

IlvNotebook::pageResized().

◆ select()

virtual void IlvNotebookPage::select ( )
virtual

Is called by the notebook when the page is selected.

Is called by the IlvNotebook::pageSelected() method when the page is selected. The default implementation shows the view associated with this page.

See also
IlvNotebook::pageSelected(), deSelect().

◆ setBackground()

void IlvNotebookPage::setBackground ( IlvColor color)

Changes the background color of the notebook page.

By default, a notebook page has no background, and thus it uses the one of its associated notebook.

See also
getFileName().

◆ setInsensitiveBitmap()

void IlvNotebookPage::setInsensitiveBitmap ( IlvBitmap bitmap)

Sets the insensitive bitmap of the page.

Allows you to set an insensitive bitmap for this notebook page. If the notebook page already owns an insensitive bitmap, it's unlocked. The new bitmap is locked.
