Just wanting to know if anybody has seen an example of a telnet/chat or other console like FLEX application where you can use the same TextArea as input/ouput area.
I've been trying to modify the app at:
http://livedocs.adobe.com/flex/3/html/17_Networking_and_communications_8.html
but so far, computer says no.
All the implementations I've seen use a combination of TextInput and TextArea.
The challenge is that we'll be using this app to telnet into some old routers and we'll need to do a fair amount of copy/pasting. Based on what I've seen, it seems that I would need to point the mouse into the TextInput in order to be able to right click and paste, which is not very sleak.....
Your thoughts,
Fran
edit Just realized that I had trimmed out what was directly pertaining to the question: I was unable to find anything that used the TextArea for input and output; see the below suggestions if custom-component suggestions are ok.
The TextArea component only fires a change event whenever a user adds input. Whenever you set the text field programmatically, a change event does not fire--you could maybe use that as a way to know what is user input and console "responses" by looking for carriage-returns (\r).
I'm unsure if you have a requirement to maintain the user's input at the bottom-most line (like a console), even after the console responds with something like auto-complete. If that's the case, then something a bit more complex would have to come into play (such as remembering where the user's input started/ended) or the requirement of a single-component console needs to be reconsidered--sleek is nice, but not always necessary.

I have a desktop application that has a form that people fill out in text boxes. If an invalid value is entered, then the box turns pink with a red border. I am using Robot framework with Squish to try and identify this error when it occurs on a certain textbox. What is the best way to do this?
Typically in QT, when actions happen they are firing signals and a slot in certain component. I'd assume that the state of the component is handled with something that triggers a signal that and the textbox receives it.
You could try to monitor what gets triggered when invalid input is given and use that in your asserts..
Another way, you might be able to read the property of your text input widget and see what changes when invalid input is given ..
Getting the internal state that results in alteration of the rendering may not be straightforward, but at least depends on which GUI technology is in use. (You have not told us yet, I think.)
A simpler approach is to use a screenshot verification point (SVP) for just that control. In that SVP, you can use a positive mask to mark a specific area that is least likely to be affected by the contents of the control (to make the SVP as robust as possible).
A similar approach is to use (verifying the actual pixel colors used for rendering on the screen) object.grabScreenshot() and use the API of the returned Image Object to query the color of an individual pixel via Image.getPixelRGB(x, y) and Image.getPixelRGBA(x, y).
My AutoIt script simulates mouse clicks. First a right click in one place, then a left click in one of many other points. I achieved that with MouseClick() and it works fine.
But now I want the script to work in "background" so I used ControlClick(). But there's no control ID. This is what I tried:
$square = Floor(Random(0,$length)) ;this one gets length of array with coordinates
;MouseClick("right", 1634,195 ,1,1) first version-works fine
ControlClick("Medivia","", "", "right",1,1634,195)
;MouseClick("left", $cordX[$square], $cordY[$square]) first version-works fine
ControlClick("Medivia","", "", "left",1 ,$cordX[$square] ,$cordY[$square])
The script clicks, but only in the place where I leave the mouse pointer. It does not move the mouse pointer by itself. Could anybody help me?
Answer Limitation: To use any of the Control* APIs from AutoIT, you're going to need to be interacting with a real Windows control.
If you just want to do "random" clicks, you probably don't need a real Windows control and should not be relying on ControlClick.
If you're trying to click on the "background" of Windows, you probably want to just minimize all open windows, which you can accomplish with WinMinimizeAll.
GUI clicks with Qt and other frameworks without real Windows Controls
Some frameworks like Qt will not give you a real Windows control for many of the default GUI buttons and the like, so when using AutoIT's Windows Info tool, as well as many of the UI spy tools out there, that info will be missing.
What you may need and I currently need is to resort are workarounds. For your case, it would help if I could see a screenshot of the sequence you're trying to automate; I could give better advice after seeing that.
For my case, I needed to click on a Quit button that had no controls and the developer told me he didn't have a way (or know a way) to add accessible names to the pop-up I was trying to hook into, even though I could hook to the main app's hWND. Luckily, that quit-box had a special color for the Quit button, which allowed me to use AutoIT's PixelSearch to locate it.
When you don't have cool helpers like that, it's usually best to determine the location of the main window, and whatever pixel-offset you need to find what you're looking for.
since there isn't any useful How-To for beginners of PyQt5, I'm stuck with a little problem about signals & slots.
I do have a lineEdit which will get a directory path by a dialog (which works fine).
If one starts the program this lineEdit is empty by default and that's ok. A button, which shall generate a file list and show it in a list view, exists. It's functionality is implemented already and working fine. This button by default is disabled when the program is started for the first time.
What I want to do now is, enabling the button when something is entered at the lineEdit and disabling it when the content is removed.
I gave it a shot with this:
self.lineEdit_SelectedDirectory.editingFinished.connect(self.pushButton_CreateFileList.setEnabled)
but I get the error that it has not enough arguments, which might be clear because there aren't any provided in this code line.
Again, this was just a guess. How would one do this?
I would love something which takes the content into account like that, that it decides whether the content is empty or not and than sets the appropriate value to the button.
thx in advance for the help.

Looks like you want the textChanged signal, since that sends the current text:
self.lineEdit_SelectedDirectory.textChanged.connect(
lambda text: self.pushButton_CreateFileList.setEnabled(bool(text)))
I have two options. I need 48 of a certain type control; it needs to respond to clicks and taps (for touch devices).
I could use Buttons, using the TextButtonStyle, and the Click event. Or I could use TextBlock, with the Tapped event.
I reckon buttons may be more "expensive" to create. OTOH, although I believe "Tapped" is also called when the user clicks the component, this makes me a little nervous due to its nomenclature, I guess.
Another difference is that a button takes up only the width necessary, whereas a TextBlock takes everything; and I want the underlying Grid to be tappable, so the TextBlock is kind of a problem that way. Is there a property that will make it more modest like the button?
There is design guidance for Windows Store apps on when and how to use buttons at http://msdn.microsoft.com/en-US/library/windows/apps/hh465470. Based on your description and this guidance, it sounds like buttons are the way to go. Responding to click events is what they were made for, and TextBlocks add the extra issues that you describe.
I want to create a combobox in flex which will take three values, Available, Unavailable, and Busy. The constraint is, I should not allow user to go directly from Unavailable to Busy. So when a User is selected Unavailable, I should keep the Busy item disabled (unselectable), but a user will be able to go directly from Available to Busy. I chouldn't find a straight forward way to disable an item in combobox in Flex. How can I do that?
Have you considered using radio buttons rather than a combo box? It's clear how to do this for radio buttons, for one thing. Also, it can often be friendlier to present the available options without requiring a click to reveal them. (Especially if, as in this case, you are adding the possibility that an option is "available, but not possible for you right now for some reason not shown in this combo-box item").
If you really want a combo-box, you can use the click event to display it in a non-standard fashion by probably changing its style; and then, if clicked anyway, Then, in the selected event, reject the choice (hopefully with an indication of why),
Or, if you want to simply remove it from the list, you can have the click listener event repopulate the source list each time, based on conditions. But that might be confusing to the user, too.

it works very well even though I added the code for being able to properly handle keyboard
events in the dropdown list
