Detailed Description

Field editor for atomic type QVariant managed using a single line edit using QtPropertyBrowser.

Note

with a little revamp this can become a full replacement for QtPropertyBrowser.

This field editor can manage

• enum (editable or not)
• string (with regexp or titleCase constraints or not)
• boolean (with custom checkbox text)
• double/int values (with min/max/decimals constraints or not)

A QtPropertyFieldEditor

• can be read only or not
• can have a place holder text (displayed when the value is empty) or not
• can be declared as mandatory. In this case if the field value is empty a warning message is sent to the CamiTKExtensionModelPresenter presenter
• can be declared as tab widget title. In this case its parent tab widget title will be interactively modified when the field edited value changes
• can be given a label to interactively update when the field edited value changes

For string setting a specific format will modify the user input to follow a given regexp everytime the user modify the field value (e.g. to ensure the field starts with an upper case letter or a number use setFormat(R"(^[A-Z0-9].*)"))

Usage example:

maximumValueEditor = new QtPropertyFieldEditor(presenter, dataModel["maximum"], "Maximum Value", "If set this will constrain the parameter maximum value", maxValue);
maximumValueEditor->setPlaceHolderText("Maximum Value");
... // use desired set methods here
myLayout->addWidget(maximumValueEditor->getWidget());

Constructor & Destructor Documentation

QtPropertyFieldEditor()

QtPropertyFieldEditor::QtPropertyFieldEditor	(	CamiTKExtensionModelPresenter *	presenter,
		VariantDataModel &	dataModel,
		const QString &	name = "",
		const QString &	description = "",
		const QVariant &	defaultValue = QVariant()
	)

Constructor If the model value is invalid (not yet present in the CamiTKExtensionModel), use the provided default value to create a new data model.

Parameters

defaultValue

if given, used to set the data model if it does not exist yet
