Programming scrolling a textarea
Hello
I am fairly new to the development of waterfalls, but have some ideas I want to implement.
I'm fighting for a few days trying to scroll a textarea semi-automatiquement.
I have a ScrollView with a textarea on the inside.
ScrollView {}
What I want to do is to be able to push a button play, which begins to scroll the text area. I looked in the forums, but in vain. Right now I'm trying something like that in my QML: function startScrolling() {} } The text box scrolls, but not smoothly; He's waiting for like 5 seconds and then jump in the fifth line. Am I missing something? THX, Johan Hello You send all updates at once while they are processed instantly and only the last is seen. The delay is due to the transformation of all accumulated messages. From one thread is probably an overdose in this situation and I think that the GUI must be adjusted to the main thread anyway. I would use a timer. There is a snippet of code to start a timer in QML (search for "QTimer"): https://developer.BlackBerry.com/Cascades/documentation/dev/integrating_cpp_qml/index.html Press the button start a timer with small interval, for example 50 msec. In the onTimeout handler immediately call scrollToPoint or stop the timer if scrolling is done. Save the current position of a property. Please note that scrollToPoint scrolls smoothly to the default destination, so if you manually update the position by small steps, you will need to disable scrolling smoothly passing a third parameter: scrView.scrollToPoint (0, location, ScrollAnimation.None) Tags: BlackBerry Developers Automatically scroll a TextArea component Hi all Is there a way to get a component TextArea to scroll automatically when the text is added to it? I had a quick glance but have not found anything that works. Thank you Brien where my_ta is the name of the TextArea (AS2) component my_ta.vPosition = my_ta.maxVPosition; my_ta.verticalScrollPosition = my_ta.maxVerticalScrollPosition; Finder - right scrolling automatically snaps back to the left Hello I use Yosemite on a Mac Book pro. Recently, I noticed a problem with my finder. I have 'column view' enabled. When I scroll to the right to see the items more far in my tree, rather than stay where I scroll finder window cling all the way back to the left, showing the folders at the root of the drive. So, I actually don't see not all folders deeper in my directory structure. I can't understand why this is happening. I hope someone can help out me! UPDATE: I discovered another problem which could be related. If I go to any program - safari, word, etc. and scroll all the way to the right, if I move the mouse over the program it will automatically scroll to the left. If I point the program, scrolling stops. Thank you! Ben SOLVED! It turns out that I needed to do something stupid - was enough to unplug and plug in my wireless mouse. Haha I've tried everything, * but * that. Go figure. Ben My touchpad scroll function does not work in Firefox 4 4 years Dell Inspiron 1520 with a Synaptics touchpad, running XP. Just downloaded FF4 last night, now discovered that my scrolling on the touchpad function no longer works. It's very irritating. If no fix is available, how to go back to the previous version of FF? Try running Firefox in questions to troubleshoot Firefox in Safe Mode. If it works properly in this configuration, then one of your modules is the culprit. By the way, I recommend you visit the Plugins check page and update your plugins. You are potentially expose your system to attack with some versions you have installed at the moment. Their update can also solve the problem with your touchpad. In case the previous steps do not resolve the problem for you, you can return to the previous version and secure that 3.6.16 as follows. I uninstall 'Gimp '? I uninstall 'Gimp '?

Cannot access Word or Powerpoint in my Start Menu "all programs"? I downloaded and paid for microsoft office 2010 student. I have a sony vaio notebook, and it works with windows 7.

Strange... in order to make it work I had to do both methods, that is to say in my TextArea subclass, I put textField.mouseWheelEnabled = false; and I created a listener to stop the spread of the mouse wheel event: addEventListener (MouseEvent.MOUSE_WHEEL, disableMouseHandler, true); It does not exactly what I need it to do, as it make sure the ScrollPane does not receive the scroll event either, but I can ignore it or find a workaround. I can install the 5.0.1 version but it won't work. I got this version works when someone elso was using my computer. I don't know how it happened, but the calculation froze and I couldn't run Firefox afterwards. I got Firefox to my computer. Downloaded the latest version once again and I tried to run it. I've done several times without success It seems that the installation is corrupt. Follow these steps. Your bookmarks, etc., customizations are stored in a different location and will become available to you even once you complete the installation. As a precaution, make a backup of your bookmarks as follows: You can use this file at any time to restore your bookmarks if that proved necessary. Simply reverse the procedure and choose "Import HTML" instead. NB. If you use a download accelerator, turn it off before trying to download Firefox. These utilities are a common cause of corrupt files, in which case you get the error message you mentioned.

He tells me that I have to update Firefox, then when I click on the button to tell it to update, it will enter in the window that says "connect to Server", but it never does.

tArea.textField.mouseWheelEnabled = false;
However, it did not work. After some research, I found some suggestions to replace the function childrenCreated of my class that extends the text box, ala
override protected function childrenCreated (): void {}
super.childrenCreated ();
textField.mouseWheelEnabled = false;
}
but this won't work in Actionscript 2. Finally, after some research, I found some suggestions to intercept and disable events, ala
this.addEventListener (ScrollEvent.SCROLL, this.disableScrollHandler);
textField.addEventListener (MouseEvent.MOUSE_WHEEL, disableMouseHandler, true);
verticalScrollBar.addEventListener (MouseEvent.MOUSE_WHEEL, disableMouseHandler, true);
addEventListener (MouseEvent.MOUSE_WHEEL, disableMouseHandler, true);
textField.addEventListener (MouseEvent.CLICK, disableMouseHandler, true);
verticalScrollBar.addEventListener (MouseEvent.CLICK, disableMouseHandler, true);
this.addEventListener (MouseEvent.CLICK, disableMouseHandler, true);
.
.
.
function disableMouseHandler(event:MouseEvent):void {}
trace ("disableClickHandler");
Event.preventDefault ();
event.stopPropagation ();
}
function disableScrollHandler(event:ScrollEvent):void {}
trace ("disableClickHandler");
Event.preventDefault ();
event.stopPropagation ();
}
But this has not as well. I have something wrong? Is it just not possible? What is the problem here?
Thank you
