On the pywinauto documentation it says that you can click a radio button using the click method:
I have already had issues using the UIA backend, since it is different to win32. In this case, there seems to be no way to click a radio button.
I tried using a window specification:
spec.window(auto_id='RadioButtonManualbackground').click()
AttributeError: Neither GUI element (wrapper) nor wrapper method 'click' were found (typo?)
It cannot find any method called click. I tried using toggle and check and those didn't work either.
I also tried clicking the radio button using the tree hierarchy:
app.Dialog.Analysis.BackgroundCorrection.ManualBackgroundCorrection.click()
pywinauto.uia_defines.NoPatternInterfaceError
Again, this didn't work with toggle or check.
Is there support for clicking a radio button using UIA backend, and how do I do it?
This might be a bit confusing, but radio button wrapper has .select() method which uses SelectionItemPattern. I've found it in test_radio_button unit test.
Proper implementation should check all possible patterns and choose the working one. So I would consider it as a bug: filed issue #549. Thanks for reporting it!
P.S. You always have method .click_input() as a workaround. It performs the most realistic click with moving the cursor.

I am working with Pywinauto to automate a Desktop Application.
At one point there could be a popup window. With findbestmatch I want to check if the popup is available. The name of the popup window is the same as of the normal window.
Is there an alternative for findbestmatch or is it the best option?
There is a pywinauto function called popup_window() which could be a good starting point for you. See link
Its listed under pywinauto.controls.hwndwrapper, which provides basic wrapping of windows controls. It will return the handle/id of any open popups or a reference to self if no popups exist.
I'm trying to add a button to my image processing script to save the high and low HSV values for my binary threshold.
According to the OpenCV 3.0 documentation here, OpenCV evidently has a function which does that.
I am writing the function like this
cv2.createButton('Button',f)
Where Button is the name of the button and f is the callback function (just an empty function)
However I keep on getting:-
AttributeError: 'module' object has no attribute 'createButton'
Apparently the same function works fine with C/C++ but it isn't working with python. Most probably because it isn't there for python (maybe) ?
How do I get around this problem?
The documentation says
Another important application of trackbar is to use it as a button or switch. OpenCV, by default, doesn’t have button functionality. So you can use trackbar to get such functionality (found at Trackbar as the Color Palette).
There is a small example how to use it as button.
cv2.namedWindow("Frame")
cv2.createButton("Back",back,None,cv2.QT_PUSH_BUTTON,1)
def back(*args):
pass
The above code shows how to implement the cv2.createButton() method.
Notes:
"Back" = text displayed on the button
back = function called when the button is pressed
the cv2 window must be created before the button
if your button is not appearing: click inside the frame, press ctrl+p or command+p (for mac) and the button menu should appear
I was searching for the reason why the button was getting attached to the control panel of QT window. I think the following extract from CV2 home page would help
The function createButton attaches a button to the control panel. Each button is added to a buttonbar to the right of the last button. A new buttonbar is created if nothing was attached to the control panel before, or if the last element attached to the control panel was a trackbar or if the QT_NEW_BUTTONBAR flag is added to the type
open cv new qt functions page link
I think it's unposible
cv2.createButton('test', GeekObject, None , cv2.QT_PUSH_BUTTON, 0)
cv2.error: OpenCV(3.4.6) C:\projects\opencv-python\opencv\modules\highgui\src\window.cpp:579: error: (-213:The function/feature is not implemented) The library is compiled without QT support in function 'cv::createButton'
I am creating an app and I need to disable a button until the user agrees to the terms. I looked online, but couldn't find anything. Any help would be great.
EDIT: I am using pyqt4.
You should use the strategy of signal/slots in Qt. When the checkbox send the checked signal you catch it with the slot defined in your button. Of course you should connect both widgets. For example:
connect(checkbox, SIGNAL(stateChanged(int)), button, SLOT(buttonStateChanged(int)));
This signals and slots maybe don't exists, and you have to create them. It is just the main idea.
I think that is a right way.
Here are some examples of connections in python, using signal/slots. And here is (maybe) what you need.
I have a PySide application with a single button that implements auto-repeat. But the auto-repeat functionality doesn't seem to be working correctly.
If I simply click and hold the button, its function is only called once no matter how long I wait or what the auto-repeat settings are. But as soon as I move the mouse, the button's functionality is called repeatedly, just as it should be.
This is with Python 2.6, PySide 1.1.2, running on Windows 7 64 bit.
self.btn.setAutoRepeat(True)
self.btn.setAutoRepeatDelay(200)
self.btn.setAutoRepeatInterval(100)
I was having a similar problem using normal QT4.x on linux. The issue was that something was connected to the clicked signal. I think it was stealing/changing the focus of the mouse. I just changed that item to connect to the the released signal. That doesn't mean you can't connect to clicked, but just be sure that there are no focus stealing side-effects.
In my python GTK project, I have a popup menu which pop-ups while typing in a particular text area. But, when type a letter popup menu get the focus and I can't type anymore in the text area until I click on the text area and grab the focus manually. I want to keep the focus to the text area as I type regularly while popup menu comes. Can anyone give tell me a way to do this. I tried widget.grab_focus() method. But it didn't solve my problem.
Also I want to know how to set the position of the popup menu. It always appears near by mouse pointer. I want it to appear near by my application.
Thanks all.
I ran into the same problem using the C API, the solution was to invoke the following functions, I presume they're approximately similar to the python equivalents:
gdk_pointer_ungrab(GDK_CURRENT_TIME);
gdk_keyboard_ungrab(GDK_CURRENT_TIME);
gtk_grab_remove(menu);
