Hi, I have not yet found the solution.I have followed this example: http://www.paraview.org/pipermail/paraview/2008-November/010217.html but still have problems. In my plugin xml file I have this:
<DoubleVectorProperty show="1" name="Result" label="Result command="GetResult" number_of_elements="1" default_values="0" information_only="1"> <SimpleDoubleInformationHelper /> </DoubleVectorProperty> In my plugin source file, I have this: double GetResult() { return m_result; } I have a class that inherit from pqAutoGeneratedObjectPanel: #include "MyPluginPanel.h" #include <QLineEdit> #include "vtkSMDoubleVectorProperty.h" #include "vtkSMProperty.h" #include "vtkSMProxy.h" MyPluginPanel::MyPluginPanel(pqProxy* object_proxy, QWidget* _parent) :pqAutoGeneratedObjectPanel(object_proxy, _parent) { p_resultWidget = this->findChild<QLineEdit*>("Result"); if( this->findChild<QLineEdit*>("Resylt") ) { qWarning() << "NULL Widget Pointer"; return; } p_resultWidget->setReadOnly(true); } MyPluginPanel::~MyPluginPanel() {} void MyPluginPanel::updateInformationAndDomains() { pqAutoGeneratedObjectPanel::updateInformationAndDomains(); updateDoubleValue(p_resultWidget, "Result", 0); } void MyPluginPanel::updateDoubleValue(QLineEdit* qLineEdit, QString property, qint32 index) { vtkSMProperty* smProperty = this->proxy()->GetProperty(property.toAscii()); if (!smProperty) { qWarning() << "SMProperty [double] was NULL for " << property.toAscii(); return; } vtkSMDoubleVectorProperty* dvp = vtkSMDoubleVectorProperty::SafeDownCast(smProperty); double value = dvp->GetElement(index); qLineEdit->setText(QString::number(value)); } The problem is that the widget resultWidget is always NULL. But I can have the good result. So, what's wrong with my code ? Why the widget doesn't appear in the GUI plugin in Paraview ? Thank you for your attention and your advice. ________________________________ De : R M <mlok...@yahoo.fr> À : paraview@paraview.org Envoyé le : Mer 15 décembre 2010, 10h 12min 20s Objet : [Paraview] Problem -> How to display informations in a plugin GUI ? Hi, I develop a plugin that and in its corresponding xml file, I have a doubleVectorProperty in which I would like to write the result of my filter and I don't want to make it editable. So, I am looking for some examples of doing this beacause I really don't know how to do this and that make a while I want to make it. I have found nothing about this in the Paraview Guide book. Here's what I have written in the plugin xml file: <DoubleVectorProperty name="GetResult" command="GetResult" information_only="1"> <SimpleDoubleInformationHelper/> </DoubleVectorProperty> <DoubleVectorProperty name="Result" command="SetResult number_of_elements="1" default_values="0.0" information_property="GetResult"> </DoubleVectorProperty> and the code in the source is: double GetResult() { return m_result; } void SetResult(double value) { m_result = value; } Then, in my code, when I would like to update this lineedit in the plugin GUI I call SetResult(myResult). But nothing happen and the lineedit in the plugin GUI is editable (which I don't want). Thank you for your advise.
