QGIS Python Dialog Box for Zooming into coordinates

Question

qid = QInputDialog()
title = "Enter Coordinates"
label = "X:" 
mode = QLineEdit.Normal    
text, ok = QInputDialog.getText(qid, title, label, mode)
print text

I am trying to create a dialog box in which I can zoom into specific coordinates. However, I'm not sure on how to get both X and the Y coordinates. The picture below shows only X.

Answer 1

Add a basic example using QInputDialog for make zoom to input coordinates

qid = QInputDialog()
canvas = iface.mapCanvas()
input, ok = QInputDialog.getText( qid, "Enter Coordinates", "Enter New Coordinates as 'xcoord,ycoord'", QLineEdit.Normal, "X" + "," + "Y")
if ok:
    x = input.split( "," )[ 0 ]
    print x
    y = input.split( "," )[ 1 ]
    print y
    if not x:
        print "Ooops!X value is missing!"
    if not y:
        print "Ooops!Y value is missing!"
    print x + "," + y
    scale=50
    rect = QgsRectangle(float(x)-scale,float(y)-scale,float(x)+scale,float(y)+scale)
    canvas.setExtent(rect)
    pt = QgsPoint(float(x),float(y))
    canvas.refresh()

Sample coord,for example is : -418795,4911670

Answer 2

QInputDialog is designed to get a single value. Is you want a more advanced input you should use a form.

You have an example on how to create a form in this stackoverflow answer (to a similar question).

Answer 3

QInputDialog() only gets a single value as explained in the documentation. One option is to change the label to "coordinates". The user could then enter both x and y in one line, separated by a comma. You can then get the individual values by using python.

x = text.split(",")[0]
y = text.split(",")[1]
