Detailed Description

a QTableView subclass for ParaView specific customizations.

pqTableView extends QTableView (in the spirit of pqTableView) to support the following:

• Avoids putting a scroll bar until the table reaches a certain length.
• Avoids taking too much space when table has fewer rows.
• Avoid grabbing scroll focus: Wheel events are not handled by the widget unless the widget has focus. Together with change in focus policy to Qt::StrongFocus instead of the default Qt::WheelFocus, we improve the widget scroll behavior when nested in other scrollable panels.

Constructor & Destructor Documentation

pqTableView()

pqTableView::pqTableView

(

QWidget *

parent = nullptr

)

~pqTableView()

pqTableView::~pqTableView ( )

override

Member Function Documentation

setMaximumRowCountBeforeScrolling()

void pqTableView::setMaximumRowCountBeforeScrolling ( int  val )

inline

Set the maximum number of rows beyond which this view should show a vertical scroll bar.

The pqTableView will keep on resizing until maximumRowCountBeforeScrolling row to avoid vertical scrolling. Set this to 0, and this will behave exactly as QTableView. Default is 0.

Definition at line 92 of file pqTableView.h.

maximumRowCountBeforeScrolling()

int pqTableView::maximumRowCountBeforeScrolling ( ) const

inline

Definition at line 93 of file pqTableView.h.

setMinimumRowCount()

void pqTableView::setMinimumRowCount ( int  val )

inline

Set the number of rows to use as the minimum to determine the size of the widget when there are fewer or no rows.

Definition at line 99 of file pqTableView.h.

minimumRowCount()

int pqTableView::minimumRowCount ( ) const

inline

Definition at line 100 of file pqTableView.h.

setPadding()

void pqTableView::setPadding ( int  val )

inline

Set the number of rows to always pad the widget with.

This is used when the actual number of rows is less than or equal to maximumRowCountBeforeScrolling for a non-zero maximumRowCountBeforeScrolling.

Definition at line 108 of file pqTableView.h.

padding()

int pqTableView::padding ( ) const

inline

Definition at line 109 of file pqTableView.h.

setModel()

void pqTableView::setModel ( QAbstractItemModel *  model )

override

Overridden to ensure the view updates its size as rows are added/removed.

setRootIndex()

void pqTableView::setRootIndex ( const QModelIndex &  index )

override

sizeHint()

QSize pqTableView::sizeHint ( ) const

override

Overridden to report size as per the state of this pqTableView.

minimumSizeHint()

QSize pqTableView::minimumSizeHint ( ) const

override

eventFilter()

bool pqTableView::eventFilter ( QObject *  watched, QEvent *  evt  )

override

Overridden to handle events from QScrollBar.

wheelEvent()

void pqTableView::wheelEvent ( QWheelEvent *  event )

override

Overridden to eat wheel events unless this->hasFocus().

Property Documentation

maximumRowCountBeforeScrolling

int pqTableView::maximumRowCountBeforeScrolling

readwrite

Maximum number of rows beyond which this view should show a vertical scroll bar.

The pqTableView will keep on resizing until maximumRowCountBeforeScrolling row to avoid vertical scrolling. Set this to 0, and this will behave exactly as QTableView. Default is 0.

Definition at line 64 of file pqTableView.h.

minimumRowCount

int pqTableView::minimumRowCount

readwrite

The number of rows to use as the minimum to determine the size of the widget when there are fewer or no rows.

Definition at line 64 of file pqTableView.h.

padding

int pqTableView::padding

readwrite

The number of rows to always pad the widget with.

This is used, so long as the total number of rows doesn't exceed the maximumRowCountBeforeScrolling. Note this gets added on top of the padding added, if any, due to minimumRowCount.
