Detailed Description

The base class for all elements which can be displayed. Actual elements need to be subclassed from QVElement.
Takes care of position, size, container and list of items.
All other functionaliy is to be implemented in the subclass.

Constructor & Destructor Documentation

QVElement::QVElement ( QDomElement  xml_desc, QString  container, QWidget *  parent = 0  )

explicit

Basic constructor for all elements.

Parameters

xml_desc	The XML <element> node
container	The parent container
parent	Parent widget, as in all Qt widgets

Will determine width, height, position, color and active color. Extracts all items which are direct children of the <element> node. They are then accessible via getItemList()

Get position of element and container. All other info is extracted in the derived classes

Member Function Documentation

QString QVElement::colorString ( QString  color )

static

Convert a Windows 8 color string to the #xxxxxx format.

Returns the color code for a Windows color name. If the name is not found, it will return the input string (as lowercase).

QString QVElement::findFilePath ( QString  name )

static

Try to find the file name in one of the directories specified by <path>

QList< int > QVElement::getGeometry

(

)

Returns x,y,w,h in this order.

QString QVElement::getItemByAction ( QString  action, int  index = 0  )

protected

Returns the item name which corresponds to the action.

Parameters

action	The action as defined in
index	If the action is contained several times in the <element> node, retrieves the n-th entry. Counting starts at 0.

Return values

An	empty string if the action is not configured or index is out of range.

QList< QString > QVElement::getItemList

(

)

Return a list of all items which have been configured inside the <element> node.

int QVElement::height ( )

protected

Height of the content in pixels

int QVElement::ofs_x ( )

protected

Content margin (x direction) in pixels

int QVElement::ofs_y ( )

protected

Content margin (y direction) in pixels

void QVElement::onContainerChanged ( QString  container )

slot

Called on ontainer change. Handled by QVElement(), to be overloaded only with reason (e.g. video element)

void QVElement::onInitCompleted ( )

virtualslot

Called when the websocket connection is established.

void QVElement::onSeriesReceived ( QString  , QMap< double, double >    )

virtualslot

Handle an incoming series. To be overloaded in QVPlot

void QVElement::onValueChanged ( QString  , QString    )

virtualslot

Handle incoming values. Will also be called after the element itself emits valueModified(). To be overloaded in a child class.

void QVElement::requestSeries ( QString  item, QString  series_type, QString  start  )

signal

Emitted to request a series. Used only by the plot element.

void QVElement::resizeEvent ( QResizeEvent *  event )

protectedvirtual

Unless you use a layout, overload this method to place Qt widgets inside the element

Reimplemented in QVWeather, QVSelector, QVGoogleCalendar, QVHeating, QVDimmer, QVPlot, QVSwitch, QVShutter, and QVFritz.

void QVElement::valueModified ( QString  , QString    )

signal

Emitted when a value has been changed actively in the element

int QVElement::width ( )

protected

Width of the content in pixels

Member Data Documentation

QString QVElement::container

protected

Container in which the element is contained

int QVElement::h

protected

Height in the grid. May be overwritten in the constructor of the derived class.

QMap<QString,QVItem> QVElement::items

protected

List of items. Key is the item name, content is a QVItem

int QVElement::w

protected

Width in the grid. May be overwritten in the constructor of the derived class.
