How to respond to changes in application status
Hi people,
I was wondering if anyone had some general tips on how I could implement the following.
My application needs to leave the GUI know in what state it is so that the GUI can respond to these changes in status.
Changes in status are not triggered by the user, but by other factors.
The idea I had was to have a variable of type integer that gets the value in the user interface when the application changes state. I could then implement a timer in the GUI that checks if the variable and reacts according to the needs.
I then did think, is there a way I can send a signal to my main application logic and have called/triggered javascript function? That would eliminate the need for a timer and make the graphical interface that is more sensitive to changes of State. But I don't know how I could implement, if possible.
I looked through the examples, but they seem to everyone respond to a user action, like I need something to answer if/when a certain condition where arrises.
Anyone have any suggestions on how to address this problem?
Thanks in advance.
Able to understand this.
QObject::connect (this, SIGNAL (mySignal ()), root, SLOT (mySlot (()));
It makes sense today, havn't quite seized this signal-> business of slot, but I happen slowly.

I bought a model site. It has a css file, /styles/screen.css
It also has a template page 'home' with the link to the style sheet within the < head > section:
"< link href="/styles/screen.css "rel ="stylesheet"type =" text/css"media ="screen"> < / link > I am tempted to change screen.css, by editing the file in the 'Develop' administration Console and pressing the 'Save' button on the file when changes are made.
However, the changes do not appear in the preview of the Page template.
However, if I do a < style > section in the head <>of the page template and put the change, it displays correctly.
It's like the Page template does not recognize changes to the screen.css.
I press "Save draft" and "Update" before you press 'Preview' to check for changes.
My question is how to fix the Page Template styles that do not respond to changes in CSS files in the text editor of 'Developing' administration Console.
I am a new user of BC and I agree it is likely a result of not knowing how the css BC.
Thanks in advance for any assistance with my issue!
Hello
I think that you too complicate the thinking problem that BC is a non-standard way of processing applications to a css file. This looks more like a cache or perhaps a code problem. However, I would be happy to take a look at your code and see if I can remember where is the problem. Try Skype me and screen-sharing and I'll see what I can do. It is probably fixed quickly :-) My ID:s 'noviumdesign '.

I just installed Firefox 5. Unfortunately, F-Secure "Application Control" now repeatedly appears "Change the Application" messages in an endless chain. It will not accept my attempts to 'Allow' the new version of Firefox. Since Firefox 5 is not compatible with F-Secure, I want to go back to my previous version of Firefox. I am very disappointed that you put me for all this trouble. How can I remove Firefox 5 and revert to the previous version of Firefox?

How can my computer change a standard user to an administrator in itself?
I have three sons. Yesterday, I noticed that the user account for them had been changed from Standard user to administrator. This son don't know how to make such a change, even if he had Admin rights. It happened several times in the past, and after correcting, it happens again.
Today, I discovered that the accounts of two of my sons have been modified by the Standard user to administrator. Why is this happening? How the computer can change the type of account alone?
I checked the status of user account control, and the cursor is on "notify me only when programs try to make changes to my computer.
Windows 7 gives me fits in too many areas.
I login or Administrator status seems to be granted just like my wife.
-> Have you ever checked if this happens when you start mode safe?
Frederik, I've responded to your suggestions several times.
-> September 5, I posted a second script and very detailed instructions. I can't see your response to it. I suspect that you have completely missed.
When I double-clicked on the program, nothing happened.
-> If you use the script I posted for you and follow the detailed instructions so the program will not work.

How to get Firefox to ignore the status of liaison visits when printing?
How to get Firefox to ignore the status of liaison visits when printing?
When I print something, visited links are a different color than unvisited links.
Is there a way to make the color even when printing?
(without changing the story, or how things look on the screen)If there isn't a way to do that, how about this by adding as a feature?
One way to do would be to create style rules customized for the printed output that hardcode the link colors for all of the printed output. Firefox supports two ways to proceed: a file userContent.css that you create in the folder settings, and a custom stylesheet applied using the Stylish extension.
However, 'one size fits all' could lead to unreadable results or ugly on some pages. If an add-on that can do adaptive way would be better. I do not know if someone has created a.
For sites that do not require a login and that are not personalized, you could launch the page in a private window (right click on the link > open in a new private window or copy the URL and then Ctrl + Shift + p, then paste it in the address bar and enter). Because private windows have their own history, the print should not reflect the history of your regular windows.

Change the application android version
Hello!
How to change an application android version in folio Builder? I need to update the application to v31 and I can't see the option.
Thank you!
You use the web app builder to http://appbuilder.digitalpublishing.acrobat.com/? If so then all you have to do is:
(1) select your existing application from the list, and then click the button change
2) click on the next button until you get to the last page and then click on submit
This will rebuild your app and automatically upgrade to the latest version (v31.1)
If you use the builder desktop client application to build a legacy application there is no rejection v31. We stopped updating the legacy Android Viewer after exit 29. You must rather build a new native Android Viewer using the link above.
