Detailed Description

Reaction to pop up a color palette chooser dialog.

pqChooseColorPresetReaction is used by pqColorEditorPropertyWidget (for example) allow the user to change the color palette. It pops up a modal dialog with color presets to select and apply. There are three ways of using this reaction:

Monitor active representation: To use this mode, pass the track_active_objects parameter to the constructor as true (default). When in this configuration, the reaction monitors the active representation (via pqActiveObjects) and allows the user to load a preset on the active representation's color/opacity transfer function using the parent action.

Monitor a specific representation: To use this mode, pass the track_active_objects parameter to the constructor as false. Then the calling code can explicitly set the representation using pqChooseColorPresetReaction::setRepresentation() method. The reaction will monitor this representation and allow user to load preset of its transfer functions.

Control a specific color transfer function: To use this mode, pass the track_active_objects parameter to the constructor as false and then set the transfer function proxy explicitly using pqChooseColorPresetReaction::setTransferFunction() method.

In all modes, the reaction will fire the presetApplied() signal to indicate a new preset has been applied. Typically one can hook that signal up to render affected views.

Member Function Documentation

◆ choosePreset

bool pqChooseColorPresetReaction::choosePreset ( const char * presetName = nullptr )

slot

Choose color preset for the representation set using setRepresentation().

Returns false if representation cannot be located or its is not using scalar coloring.

◆ setRepresentation [1/2]

void pqChooseColorPresetReaction::setRepresentation	(	pqDataRepresentation *	repr,
		int	selectedPropertiesType
	)

slot

Set the data representation explicitly when track_active_objects is false.

◆ setRepresentation [2/2]

void pqChooseColorPresetReaction::setRepresentation ( pqDataRepresentation * repr )

inlineslot

Set the data representation explicitly when track_active_objects is false.

Definition at line 71 of file pqChooseColorPresetReaction.h.

◆ setActiveRepresentation

void pqChooseColorPresetReaction::setActiveRepresentation ( )

slot

Set the data representation explicitly when track_active_objects is false.

◆ setTransferFunctions

void pqChooseColorPresetReaction::setTransferFunctions ( std::vector< vtkSMProxy *> lut )

slot

Set the transfer function proxy.

This can be used, instead of setRepresentation() when track_active_objects was false to directly set the transfer function proxy on which to apply the preset.

◆ setTransferFunction

void pqChooseColorPresetReaction::setTransferFunction ( vtkSMProxy * lut )

inlineslot

Set the transfer function proxy.

This can be used, instead of setRepresentation() when track_active_objects was false to directly set the transfer function proxy on which to apply the preset.

Definition at line 85 of file pqChooseColorPresetReaction.h.

◆ updateEnableState

void pqChooseColorPresetReaction::updateEnableState ( )

overrideslot

Updates the enabled state.

Applications need not explicitly call this.

◆ setAllowsRegexpMatching

void pqChooseColorPresetReaction::setAllowsRegexpMatching ( bool allow )

inlineslot

Show/hide widget in the dialog.

Allows a regexp as user entry to do the matching between data values and preset. Intended to be used for series preset.

Definition at line 101 of file pqChooseColorPresetReaction.h.

◆ regularExpression

QRegularExpression pqChooseColorPresetReaction::regularExpression ( )

slot

Return the regular expression specified in the Dialog.

◆ loadAnnotations

bool pqChooseColorPresetReaction::loadAnnotations ( )

slot

Return if annotations should be loaded.

◆ presetApplied

void pqChooseColorPresetReaction::presetApplied ( const QString & )

signal

fired every time a preset is applied.

◆ onTriggered()

void pqChooseColorPresetReaction::onTriggered ( )

overrideprotectedvirtual

Called when the action is triggered.

Reimplemented from pqReaction.
