\section{\class{wxVarHVScrollHelper}}\label{wxvarhvscrollhelper}
|
|
|
|
This class provides functions wrapping the
|
|
\helpref{wxVarHScrollHelper}{wxvarhscrollhelper} and
|
|
\helpref{wxVarVScrollHelper}{wxvarvscrollhelper} classes, targeted for
|
|
scrolling a window in both axis using
|
|
\helpref{wxHVScrolledWindow}{wxhvscrolledwindow}. Since this class is also
|
|
the join class of the horizontal and vertical scrolling functionality, it
|
|
also addresses some wrappers that help avoid the need to specify class scope
|
|
in your wxHVScrolledWindow-derived class when using wxVarScrollHelperBase
|
|
functionality.
|
|
|
|
Like all three of it's scroll helper base classes, this class is mostly only
|
|
useful to those classes built into wxWidgets deriving from here, and this
|
|
documentation is mostly only provided for referencing those functions
|
|
provided. You will likely want to derive your window from wxHVScrolledWindow
|
|
rather than from here directly.

\membersection{wxVarHVScrollHelper::wxVarHVScrollHelper}\label{wxvarhvscrollhelperwxvarhvscrollhelper}
|
|
|
|
\func{}{wxVarHVScrollHelper}{\param{wxWindow* }{winToScroll}}
|
|
|
|
Constructor taking the target window to be scrolled by this helper class.
|
|
This will attach scroll event handlers to the target window to catch and
|
|
handle scroll events appropriately.
|
|
|
|
|
|
\membersection{wxVarHVScrollHelper::EnablePhysicalScrolling}\label{wxvarhvscrollhelperenablephysicalscrolling}
|
|
|
|
\func{void}{EnablePhysicalScrolling}{\param{bool }{vscrolling = true}, \param{bool }{hscrolling = true}}
|
|
|
|
With physical scrolling on (when this is {\tt true}), the device origin is
|
|
changed properly when a \rtfsp\helpref{wxPaintDC}{wxpaintdc} is prepared,
|
|
children are actually moved and laid out properly, and the contents of the
|
|
window (pixels) are actually moved. When this is {\tt false}, you are
|
|
responsible for repainting any invalidated areas of the window yourself to
|
|
account for the new scroll position.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{vscrolling}{Specifies if physical scrolling should be turned on when scrolling vertically.}
|
|
|
|
\docparam{hscrolling}{Specifies if physical scrolling should be turned on when scrolling horizontally.}
|
|
|
|
|
|
\membersection{wxVarHVScrollHelper::GetRowColumnCount}\label{wxvarhvscrollhelpergetrowcolumncount}
|
|
|
|
\constfunc{wxSize}{GetRowColumnCount}{\void}
|
|
|
|
Returns the number of columns and rows the target window contains.
|
|
|
|

|
|
|
|
\helpref{SetRowColumnCount()}{wxvarhvscrollhelpersetrowcolumncount}
|
|

|
|
|
\membersection{wxVarHVScrollHelper::GetVisibleBegin}\label{wxvarhvscrollhelpergetvisiblebegin}
|
|
|
|
\constfunc{wxPosition}{GetVisibleBegin}{\void}
|
|
|
|
Returns the index of the first visible column and row based on the current
|
|
scroll position.
|
|
|
|
|
|
\membersection{wxVarHVScrollHelper::GetVisibleEnd}\label{wxvarhvscrollhelpergetvisibleend}
|
|
|
|
\constfunc{wxPosition}{GetVisibleEnd}{\void}
|
|
|
|
Returns the index of the last visible column and row based on the scroll
|
|
position. This includes any partially visible columns or rows.
|
|
|
|
|
|
\membersection{wxVarHVScrollHelper::VirtualHitTest}\label{wxvarhvscrollhelpervirtualhittest}
|
|
|
|
\constfunc{wxPosition}{VirtualHitTest}{\param{wxCoord }{x}, \param{wxCoord }{y}}
|
|
|
|
\constfunc{wxPosition}{VirtualHitTest}{\param{const wxPoint\& }{pos}}
|
|
|
|
Returns the virtual scroll unit under the device unit given accounting for
|
|
scroll position or {\tt wxNOT\_FOUND} (for the row, column, or possibly both
|
|
values) if none.
|
|
|
|
|
|
\membersection{wxVarHVScrollHelper::IsVisible}\label{wxvarhvscrollhelperisvisible}
|
|
|
|
\constfunc{bool}{IsVisible}{\param{size\_t }{row}, \param{size\_t }{column}}
|
|
|
|
\constfunc{bool}{IsVisible}{\param{const wxPosition\& }{pos}}
|
|
|
|
Returns {\tt true} if both the given row and column are currently visible
|
|
(even if only partially visible) or {\tt false} otherwise.
|
|
|
|
|
|
\membersection{wxVarHVScrollHelper::RefreshRowColumn}\label{wxvarhvscrollhelperrefreshrowcolumn}
|
|
|
|
\func{virtual void}{RefreshRowColumn}{\param{size\_t }{row}, \param{size\_t }{column}}
|
|
|
|
\func{virtual void}{RefreshRowColumn}{\param{const wxPosition\& }{pos}}
|
|
|
|
Triggers a refresh for just the area shared between the given row and column
|
|
of the window if it is visible.
|
|
|
|
|
|
\membersection{wxVarHVScrollHelper::RefreshRowsColumns}\label{wxvarhvscrollhelperrefreshrowscolumns}

|
|
|
|
\func{virtual void}{RefreshRowsColumns}{\param{const wxPosition\& }{from}, \param{const wxPosition\& }{to}}
|
|
|
|
Triggers a refresh for the visible area shared between all given rows and
|
|
columns (inclusive) of the window. If the target window for both orientations
|
|
is the same, the rectangle of cells is refreshed; if the target windows
|
|
differ, the entire client size opposite the orientation direction is
|
|
refreshed between the specified limits.
|
|
|
|
|
|

|
|
|

|
derived class must provide the sizes for all rows and columns with indices up
|
|
to the ones given here in it's \helpref{OnGetRowHeight()}{wxvarvscrollhelperongetrowheight}
|
|
