[PySide] search widget

[Sebastian Elner]

This is the search line edit class I use. The only thing to do is pass 
the SearchLineEdit two valid pixmaps for the icons. I use the icons from 
the tango desktop project. Notice that you can easily make the magnifier 
icon a button with a menu, to have the user select the "search engine" 
(uncomment the lines below). Tested with PyQt only.

from PySide import QtCore, QtGui

class SearchLineEdit(QtGui.QLineEdit):

     def __init__(self, searchPixmap, clearPixmap, parent = None):
         QtGui.QLineEdit.__init__(self, parent)

         self.clearButton = QtGui.QToolButton(self)
         self.clearButton.setIcon(QtGui.QIcon(clearPixmap))
         self.clearButton.setIconSize(clearPixmap.size())
         self.clearButton.setCursor(QtCore.Qt.ArrowCursor)
         self.clearButton.setStyleSheet("QToolButton { border: none; 
padding: 0px; }")
         self.clearButton.hide()
         self.clearButton.clicked.connect(self.clear)
         self.textChanged.connect(self.updateCloseButton)


         self.searchButton = QtGui.QToolButton(self)
         self.searchButton.setIcon(QtGui.QIcon(searchPixmap))
         self.searchButton.setIconSize(searchPixmap.size())
         self.searchButton.setStyleSheet("QToolButton { border: none; 
padding: 0px; }")

         frameWidth = 
self.style().pixelMetric(QtGui.QStyle.PM_DefaultFrameWidth)
         self.setStyleSheet("QLineEdit { padding-left: %spx; 
padding-right: %spx; } " % (self.searchButton.sizeHint().width() + 
frameWidth + 1, self.clearButton.sizeHint().width() + frameWidth + 1))
         msz = self.minimumSizeHint()
         self.setMinimumSize(max(msz.width(), 
self.searchButton.sizeHint().width() + 
self.clearButton.sizeHint().width() + frameWidth * 2 + 2),
                             max(msz.height(), 
self.clearButton.sizeHint().height() + frameWidth * 2 + 2))

#        self.searchMenu = QtGui.QMenu(self.searchButton)
#        self.searchButton.setMenu(self.searchMenu)
#        self.searchMenu.addAction("Google")
#        self.searchButton.setPopupMode(QtGui.QToolButton.InstantPopup)


     def resizeEvent(self, event):
         sz = self.clearButton.sizeHint()
         frameWidth = 
self.style().pixelMetric(QtGui.QStyle.PM_DefaultFrameWidth)
         self.clearButton.move(self.rect().right() - frameWidth - 
sz.width(),
                               (self.rect().bottom() + 1 - sz.height()) / 2)
         self.searchButton.move(self.rect().left() + 1,
                               (self.rect().bottom() + 1 - sz.height()) / 2)

     def updateCloseButton(self, text):
         if text:
             self.clearButton.setVisible(True)
         else:
             self.clearButton.setVisible(False)


app = QtGui.QApplication([])
w = SearchLineEdit(QtGui.QPixmap(r"system-search.png"), 
QtGui.QPixmap(r"process-stop.png"))
w.show()
app.exec_()
