guiqwt.signals
--------------
In `guiqwt` version 2, the `signals` module used to contain constants defining
the custom Qt SIGNAL objects used by `guiqwt`: the signals definition were
gathered here to avoid misspelling signals at connect and emit sites (with
old-style signals, any misspelled signal string would have lead to a silent
failure of signal emission or connection).
Since version 3, to ensure PyQt5 compatibility, `guiqwt` is using only
new-style signals and slots.
However, all signals are summarized below, in order to facilitate migration
from `guiqwt` v2 to `guiqwt` v3.
Signals available:
:py:data:`guiqwt.baseplot.BasePlot.SIG_ITEM_MOVED`
Emitted by plot when an IBasePlotItem-like object was moved from
(x0, y0) to (x1, y1)
Arguments: item object, x0, y0, x1, y1
:py:data:`guiqwt.baseplot.BasePlot.SIG_MARKER_CHANGED`
Emitted by plot when a `guiqwt.shapes.Marker` position changes
Arguments: `guiqwt.shapes.Marker` object
:py:data:`guiqwt.baseplot.BasePlot.SIG_AXES_CHANGED`
Emitted by plot when a `guiqwt.shapes.Axes` position (or angle) changes
Arguments: `guiqwt.shapes.Axes` object
:py:data:`guiqwt.baseplot.BasePlot.SIG_ANNOTATION_CHANGED`
Emitted by plot when an annotations.AnnotatedShape position changes
Arguments: annotation item
:py:data:`guiqwt.baseplot.BasePlot.SIG_RANGE_CHANGED`
Emitted by plot when a shapes.XRangeSelection range changes
Arguments: range object, lower_bound, upper_bound
:py:data:`guiqwt.baseplot.BasePlot.SIG_ITEMS_CHANGED`
Emitted by plot when item list has changed (item removed, added, ...)
Arguments: plot
:py:data:`guiqwt.baseplot.BasePlot.SIG_ACTIVE_ITEM_CHANGED`
Emitted by plot when selected item has changed
Arguments: plot
:py:data:`guiqwt.baseplot.BasePlot.SIG_ITEM_REMOVED`
Emitted by plot when an item was deleted from the itemlist or using
the delete item tool
Arguments: removed item
:py:data:`guiqwt.baseplot.BasePlot.SIG_ITEM_SELECTION_CHANGED`
Emitted by plot when an item is selected
Arguments: plot
:py:data:`guiqwt.baseplot.BasePlot.SIG_PLOT_LABELS_CHANGED`
Emitted (by plot) when plot's title or any axis label has changed
Arguments: plot
:py:data:`guiqwt.baseplot.BasePlot.SIG_AXIS_DIRECTION_CHANGED`
Emitted (by plot) when any plot axis direction has changed
Arguments: plot
:py:data:`guiqwt.histogram.LevelsHistogram.SIG_VOI_CHANGED`
Emitted by "contrast" panel's histogram when the lut range of some items
changed (for now, this signal is for guiqwt.histogram module's internal
use only - the 'public' counterpart of this signal is SIG_LUT_CHANGED,
see below)
:py:data:`guiqwt.baseplot.BasePlot.SIG_LUT_CHANGED`
Emitted by plot when LUT has been changed by the user
Arguments: plot
:py:data:`guiqwt.baseplot.BasePlot.SIG_MASK_CHANGED`
Emitted by plot when image mask has changed
Arguments: MaskedImageItem object
:py:data:`guiqwt.baseplot.BasePlot.SIG_CS_CURVE_CHANGED`
Emitted by cross section plot when cross section curve data has changed
Arguments: plot
:py:data:`guiqwt.panels.PanelWidget.SIG_VISIBILITY_CHANGED`
Emitted for example by panels when their visibility has changed
Arguments: state (boolean)
:py:data:`guiqwt.tools.InteractiveTool.SIG_VALIDATE_TOOL`
Emitted by an interactive tool to notify that the tool has just been
"validated", i.e. <ENTER>, <RETURN> or <SPACE> was pressed
Arguments: filter
:py:data:`guiqwt.tools.InteractiveTool.SIG_TOOL_JOB_FINISHED`
Emitted by an interactive tool to notify that it is finished doing its job
:py:data:`guiqwt.tools.OpenFileTool.SIG_OPEN_FILE`
Emitted by an open file tool
:py:data:`guiqwt.tools.ImageMaskTool.SIG_APPLIED_MASK_TOOL`
Emitted by the ImageMaskTool when applying the shape-defined mask
