Detailed Description

Class for zoomable windows.

Stores the original size of the window, so that Zooming is always computed from this data, and thus rounding errors are avoided.

float wxZoomData::GetZoom (   )  [inline]

Returns the set zoom factor. Definition at line 72 of file resizec.h. References m_zoom.

void wxZoomData::Move (  int  xpos, int  ypos )

Updates the original window position. Definition at line 64 of file resizec.cpp. References m_currRect, m_orgPos, and m_zoom. Referenced by wxResizeableControl::DoSetSize(), and wxResizeableControl::OnMove().

void wxZoomData::SetCurrentZoom (  float  zoom  )  [inline]

Changes zoom factor without resizing the window. Definition at line 63 of file resizec.h. References m_orgPos, m_orgSize, and m_zoom. Referenced by wxResizeableControl::SetCurrentZoom().

void wxZoomData::SetSize (  int  width, int  height )

void wxZoomData::SetZoomRect (  wxWindow *  Window, float  zoom, int  curxoffs, int  curyoffs, int  newxoffs, int  newyoffs )

Set new zoom factor (position and size). curxoffs and curyoffs are the current offset values (e. g. scroll position) in absolute size (unzoomed) newxoffs and newyoffs are the new offset values Definition at line 76 of file resizec.cpp. References m_currRect, m_orgPos, m_orgSize, and m_zoom.

void wxZoomData::SetZoomSize (  wxWindow *  Window, float  zoom )  [inline]
