Detailed Description

Represents a column layout.

Column layouts are used to represent the view in different ways depending on the device we are running our application.

If, for example, you run the application in a tablet that has more screen the application could use more columns than running in a phone.

unity::scopes::qt::QColumnLayout::QColumnLayout ( int num_of_columns )

explicit

Creates a layout definition that expects num_of_columns columns to be added with ColumnLayout::add_column.

Parameters

num_of_columns The number of columns for the layout.

Exceptions

unity::InvalidArgumentException for an invalid number of columns.

void unity::scopes::qt::QColumnLayout::add_column ( QVector< QString > widget_ids )

Adds a new column and assigns widgets to it.

ColumnLayout expects exactly the number of columns passed to the constructor to be created with the add_column method.

Exceptions

unity::LogicException	if an attempt is made to add more columns than specified in the constructor.
unity::LogicException	from unity::scopes::qt::QPreviewReply::register_layout if a layout has fewer columns than specified in the constructor.

QVector<QString> unity::scopes::qt::QColumnLayout::column ( int index ) const

Retrieve the list of widgets for given column.

Parameters

index The index of a column.

Exceptions

unity::InvalidArgumentException if the index is invalid.

int unity::scopes::qt::QColumnLayout::number_of_columns ( ) const

noexcept

Get the number of columns expected by this layout as specified in the constructor.

int unity::scopes::qt::QColumnLayout::size ( ) const

noexcept

Get the current number of columns in this layout.
