Detailed Description

this QComboox descendent with en hanced features (e.g. can be set to read-only, editingFinished() signal, ...)

Added features are:

• setReadonly() slot, which shows the combobox in the standardway, but prevents editing (and deletes any key-press events)
• editingFinished() signal, which is emitted when "return" or "enter" key is pressed

Usage example:

 
    JKQTEEnhancedComboBox* cmbReadOnly=new JKQTEEnhancedComboBox(wid);
    cmbReadOnly->setReadonly(true);
    cmbReadOnly->setEditable(false);
    cmbReadOnly->addItem("item 1");
    cmbReadOnly->addItem("item 2");
    cmbReadOnly->addItem("item 3");
    cmbReadOnly->addItem("item 4");
    cmbReadOnly->setCurrentIndex(1);
    connect(cmbReadOnly, &JKQTEEnhancedComboBox::editingFinished,
            [labcmbReadOnly, cmbReadOnly]() {
                labcmbReadOnly->setText(tr("editingFinished: text=%1").arg(cmbReadOnly->currentText()));
            });
 
    JKQTEEnhancedComboBox* cmbReadOnlyEditable=new JKQTEEnhancedComboBox(wid);
    cmbReadOnlyEditable->setReadonly(true);
    cmbReadOnlyEditable->setEditable(true);
    cmbReadOnlyEditable->addItem("item 1");
    cmbReadOnlyEditable->addItem("item 2");
    cmbReadOnlyEditable->addItem("item 3");
    cmbReadOnlyEditable->addItem("item 4");
    cmbReadOnlyEditable->setCurrentIndex(1);
    connect(cmbReadOnlyEditable, &JKQTEEnhancedComboBox::editingFinished,
            [labcmbReadOnlyEditable, cmbReadOnlyEditable]() {
                labcmbReadOnlyEditable->setText(tr("editingFinished: text=%1").arg(cmbReadOnlyEditable->currentText()));
            });
 
    JKQTEEnhancedComboBox* cmbEditable=new JKQTEEnhancedComboBox(wid);
    cmbEditable->addItem("item 1");
    cmbEditable->addItem("item 2");
    cmbEditable->addItem("item 3");
    cmbEditable->addItem("item 4");
    cmbEditable->setCurrentIndex(1);
    cmbEditable->setEditable(true);
    connect(cmbEditable, &JKQTEEnhancedComboBox::editingFinished,
            [labcmbEditable, cmbEditable]() {
                labcmbEditable->setText(tr("editingFinished: text=%1").arg(cmbEditable->currentText()));
            });
