- qt4->qt5 - in built qt5 6.1.5 because rhel7 is not upto date with qt5, removed findqwt.cmake - made a fix in qwt lib (qwt_plot_layout.h) to work with 5.15 and lower versions for qrect constr. - qt5 forms fixed, qt4 many hard coding forms switched to forms including qtabwidget, scrolls etc, fonts moved to forms - docking option enabled by default, removed option to disable docking feature from "Mode" - added qVersionResolve utility functions to handle compatibility before and after qt5.12 - qtplots (ian's code) takes in gain mode enable to set some settings within the class, with proper gain plot ticks - ensure gain plots have no zooming of z axis in 2d and y axis in 1d - removed placeholder text in qpalette in main window form as its not supportd until 5.12 (so using qt5.9 designer insted of qt5.15 to cope) - tab order Servers: - fixed some error messages that were empty for fail in funcs (mostly minor as if this error, major issues)

\brief QwtPlotZoomer provides stacked zooming for a plot widget
|
|
|
|
QwtPlotZoomer selects rectangles from user inputs ( mouse or keyboard )
|
|
translates them into plot coordinates and adjusts the axes to them.
|
|
The selection is supported by a rubber band and optionally by displaying
|
|
the coordinates of the current mouse position.
|
|
|
|
Zooming can be repeated as often as possible, limited only by
|
|
maxStackDepth() or minZoomSize(). Each rectangle is pushed on a stack.
|
|
|
|
The default setting how to select rectangles is
|
|
a QwtPickerDragRectMachine with the following bindings:
|
|
|
|
- QwtEventPattern::MouseSelect1\n
|
|
The first point of the zoom rectangle is selected by a mouse press,
|
|
the second point from the position, where the mouse is released.
|
|
|
|
- QwtEventPattern::KeySelect1\n
|
|
The first key press selects the first, the second key press
|
|
selects the second point.
|
|
|
|
- QwtEventPattern::KeyAbort\n
|
|
Discard the selection in the state, where the first point
|
|
is selected.
|
|
|
|
To traverse the zoom stack the following bindings are used:
|
|
|
|
- QwtEventPattern::MouseSelect3, QwtEventPattern::KeyUndo\n
|
|
Zoom out one position on the zoom stack
|
|
|
|
- QwtEventPattern::MouseSelect6, QwtEventPattern::KeyRedo\n
|
|
Zoom in one position on the zoom stack
|
|
|
|
- QwtEventPattern::MouseSelect2, QwtEventPattern::KeyHome\n
|
|
Zoom to the zoom base
|
|
|
|
The setKeyPattern() and setMousePattern() functions can be used
|
|
to configure the zoomer actions. The following example
|
|
shows, how to configure the 'I' and 'O' keys for zooming in and out
|
|
one position on the zoom stack. The "Home" key is used to
|
|
"unzoom" the plot.
|
|
|
|
\code
|
|
zoomer = new QwtPlotZoomer( plot );
|
|
zoomer->setKeyPattern( QwtEventPattern::KeyRedo, Qt::Key_I, Qt::ShiftModifier );
|
|
zoomer->setKeyPattern( QwtEventPattern::KeyUndo, Qt::Key_O, Qt::ShiftModifier );
|
|
zoomer->setKeyPattern( QwtEventPattern::KeyHome, Qt::Key_Home );
|
|
\endcode
|
|
|
|
QwtPlotZoomer is tailored for plots with one x and y axis, but it is
|
|
allowed to attach a second QwtPlotZoomer ( without rubber band and tracker )
|
|
for the other axes.
|
|
|
|
\note The realtime example includes an derived zoomer class that adds
|
|
scrollbars to the plot canvas.
