Qt Draw/drag and drop

deranjer

I have a question about Qt development gui options. I want to create a garden bed layout program, so I want to create a "draw" interface, where the user can "draw" on a grid to lay out the garden beds (and right click on the squares to "plant seeds"). Is this possible in Qt?

This link is http://i59.tinypic.com/eg2wkh.png the start of my gui prototype for the main window. I drew the graph manually right now, and if I need to I can do that again.

Hi,

You have several way to do it, e.g. QML, QGraphicsView. You should have a look at the demos & examples from the documentation to see which solution provides what's you want.

Hope it helps

I'm using Pyside to create the application (I'm very new to python and QT), and have the following code to create the background "grid":

@class mainWindow(QtGui.QMainWindow, Ui_mainWindow):
def init(self, parent=None):
QtGui.QMainWindow.init(self, parent)
self.setupUi(self) #draw all the UI elements
#drawing the SFG grid
scene = QtGui.QGraphicsScene()
for x in range (-500, 500, 60):
for y in range (-300, 300, 60):
scene.addRect(QtCore.QRectF(x,y,60,60))

    self.gridView.setScene(scene)@

Now I would like to draw a bold line around a set number of boxes (defining bed sizes) and then be able to click on individual boxes and add pictures to each box (showing plants).

This works, but I can't create a mouse event in the same class apparently, but I can't seem to create a scene class that works:
@class createScene(QtGui.QGraphicsScene):
def init(self, parent=None):
QtGui.QGraphicsScene.init(self, parent)
gridScene = QtGui.QGraphicsScene()
for x in range (-500, 500, 60):
for y in range (-300, 300, 60):
gridScene.addRect(QtCore.QRectF(x,y,60,60)) @

How can I capture mouse events in the scene, and how do I select the boxes I created?

Then, you should really have a look at the QGraphicsScene related examples and classes, they will provide you with the building blocks you need

Unfortunately, the direct Qt documentation doesn't help me much, as I don't know any C++. I've read the PySide documentation on it, but that doesn't provide any examples on how to code it, so I don't really have any way to figure out how to program it.

Have a look "here":https://qt.gitorious.org/pyside/pyside-examples/source/060dca8e4b82f301dfb33a7182767eaf8ad3d024:examples there's the example you've been searching :)
