Detailed Description

Python widget control.

The python widget control takes ownership if a Python object instance and delegates the C++ calls to the Python code.

The python instance needs to implement a method named:

def createWidget(self, control, parent):

where control is the owning MLABPythonWidgetControl and parent it the parent QWidget.

If the control should have MDL children, implement a

def setupChildren(self):

method and use MLABPythonWidgetControl::createChildWidget() to create child widgets.

If you want to know when your control gets destroyed, implement:

def controlDestroyed(self):

Member Function Documentation

addCommand

MLABPythonWidgetControlCommand* MLABPythonWidgetControl::addCommand ( MLABTree *  tree )

slot

add a scripting command for the given tree.

The returned object has a MLABPythonWidgetControlCommand::call() method which can be called to emit the command (and thus call the attached scripting function with the arguments passed to call). Currently only up to 4 arguments are supported.

addFieldListener

void MLABPythonWidgetControl::addFieldListener ( MLABField *  field, PyObject *  callable  )

slot

add a fieldlistener for the given field (field can be read from an MDL tree using lookupField())

createChildWidget

QWidget* MLABPythonWidgetControl::createChildWidget ( MLABTree *  tree, QWidget *  parent = nullptr  )

slot

Create a child widget from given MDL tree, the returned widget needs to be added to a Qt layout.

If no parent is given, the main widget of the control is used. This should only be called from the setupChildren() Python method.

createMenu

QMenu* MLABPythonWidgetControl::createMenu ( MLABTree *  tree, QWidget *  owner  )

slot

create a QMenu from MDL SubMenu items given in tree.

findTree

MLABTree* MLABPythonWidgetControl::findTree ( const QString &  name )

slot

Searches inside the MDL tree of the control (including the MDL prototype definition for that control) and returns the first tree with given name (case insensitive).

For more complex searches, you can directly access the MDL tree via MLABWidgetControl::tree().

findTreeBoolValue

bool MLABPythonWidgetControl::findTreeBoolValue ( const QString &  name, bool  defaultValue = false  )

slot

Searches inside the MDL tree of the control (including the MDL prototype definition for that control) and returns the first tree's double value with given name (case insensitive).

findTreeDoubleValue

double MLABPythonWidgetControl::findTreeDoubleValue ( const QString &  name, double  defaultValue = 0.  )

slot

Searches inside the MDL tree of the control (including the MDL prototype definition for that control) and returns the first tree's double value with given name (case insensitive).

findTreeIntValue

int MLABPythonWidgetControl::findTreeIntValue ( const QString &  name, int  defaultValue = 0  )

slot

Searches inside the MDL tree of the control (including the MDL prototype definition for that control) and returns the first tree's integer value with given name (case insensitive).

findTreeStringValue

QString MLABPythonWidgetControl::findTreeStringValue ( const QString &  name, const QString &  defaultValue = QString()  )

slot

Searches inside the MDL tree of the control (including the MDL prototype definition for that control) and returns the first tree's value with given name (case insensitive).

lookupField

MLABField* MLABPythonWidgetControl::lookupField ( MLABTree *  tree )

slot

lookup the field given by the value of the passed tree

object

QVariant MLABPythonWidgetControl::object ( )

slot

return the python object for scripting
