Small controls in a Qt application

Some parts of Qt controls in my playbook application are very small (in particular, the arrows in a QDateEdit and a QSpinBox). It's really hard to click on them with my fat finger!

Someone knows what to do?

I was experimenting with the Qt Widgets, a few months ago I ran into this problem too.

My last suggestion would be to use QML instead of QWidgets, because they are suited for touch-screen interfaces. In addition, it will facilitate your progress to the waterfalls.

That being said, if you want to solve your questions now, I can make some suggestions. Basically, Qt has failed to a certain style of user interface, where the sizes are "small". It is expected that you use a mouse and a keyboard, so it is size controls according to this.

The solution is to make the biggest checks. Although each widget has its own methods to do so, the beauty of Qt is the ability to apply stylesheets for your entire application. It is excellent because you can have a consistent look in all of your applications.

For your scenario, you can use the style sheet to adjust the default sizes for controls that you use.

This link should help you get started with everything you need to accomplish what you're looking for.

Good luck!

  • PID control Windows THIS Labview application

    Hello

    I want to build an application that will control the temperature in ovens, using the PID command. The application will run in a controller (or a computer touch panel) with windows CE OS. I have Labview 8.6, the PID control 8.6 toolkit and Touch panel 8.6 module. The problem is that the vi PID does not seem to work on the touch panel module.

    Is it possible to implement the PID control in a Labview windows CE application?

    Thanks in advance.

    I think that with a timed loop you can run a reasonable opportunity to 1 mSecond. I think 1 mSecond is the lower limit for the real-time systems like Windows/windows CE. And if you have the PID toolkit that will provide you with the features you need. You need not additional tools kit this PID. This because the touch panel module run under your standard Labview environment. But I don't know if the functions of the tool of PID like fuzzy logic are compatible with THIS. Have you also thought Windows Embedded as an operating system for your module. With windows Embedded, you can run standard Labview built of exe files

    Both Windows Embedded XP Embedded can be dragged

  • Cursor controlled by a web application home page

    I use a homepage slider that works fine, but when I have a web application the control, he can't seem to find the images. This is my list template:

    < div data-inch = "{tag_thumb image - 100w 75 h} ' data-src =" {tag_large image - 960w 480 h} ">"

    < div class = "camera_caption fadeFromBottom" >

    < h2 > {tag_name_nolink} < / h2 >

    < p > {tag_project brief description}-< a href = "{link tag_project}" > LEARN more < /a >

    < /p > < / div > < / div >

    The dynamic tags "tag_thumb image - 100w 75 h'and'tag_large image - 960w 480 h" are fields defined in the images.

    This is what works:

    "< div data-thumb="/hpprojects/images/slides/thumbs/slide1.jpg "data-src="/hpprojects/images/slides/slide1.jpg "> < div class ="camera_caption fadeFromBottom"> < h2 > project title 1 < / h2 > < brief description p > goes here - < a href =" # "> LEARN more < /a > < /p > < / div > < / div >.

    The strange thing is that, when I insert the path of the image in the list template, and not the dynamic tag, it works.  However, that defeated the purpose of the use of the web application.

    Can someone please help?

    Some examples of work...

    With web app (does not work) http://gbcookeinc.BusinessCatalyst.com/slider.html

    Hey there,

    I bet that you do just the image tag as is?

    Custom field image will make an image wrapped in a link to the detailed view, _nolink option will make the image without link. _Value is what you need to get the location of the raw source of the image.

    Thank you
    Arun

    Fixed it :)
    I had to put the following parameter: IntradocServerPort = 4444

    When I ran my program I saw results in my table. Also, I do not see the warning...

    I used the search instead of getItems operation.
    I need to set the path to "/" and recursive to true in order to see the results in my table.

    When I use the getItems operation and set the path to "/" and run the file, I get a single record with the record of the contribution.

    I notice in your links, you use links to set the path, so I think you want the user to go through the files and update the list when the user selects a folder, correct?

    To test your connection, set the path in your links to the getItems operation to / instead to your EL expression.
    If you have a result, that there is something wrong with your logic. If you do not see a result, there is something else wrong.

    For example, here are my links:

    
    
      
      
        
        
      
      
        
          
          
        
        
          
            
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
            
          
        
      
    
    

    If you do not see results when "code you" the path to /.

  • control labview through labview application.

    Hello guys, I was wondering if I can do what the title says, let me explain, I have only (executable) Labview application on my PC, I don't have the source code for this application, I take this opportunity to test the signals from some analog cards.

    Go, though the procedure to test this its fully manual, you must be clicking on things like 'accept' and it gives you dradles result at the same time, I want to see if its posible to have an another executable labview that does all this instead of me and Recollet entry information and present a summary at the end. It's like automate the test.

    Thanks in advance

    You might be able to do this via the server of VI.  And even that would be a lot of work to make it work.  You will need to know a lot about code in the executable file to run.  In all honesty, he would probably be easier for you to rewrite the other program to do what you ask.

  • Control by different user applications

    Hai all,

    We currently use R12 in solaris... We have r12 on 2 servers (db and application)... application is done by the user
    appltest... He is the owner of the R12 technology stack. Now we need to monitor the application process at the level of the BONE by another
    User OS which has no privileges on the directory of the application... How we can use this user to check the status of the various R12
    Oracle application process...

    All entries?


    Kai

    You can use the ps command to monitor active processes, but it is not enough. You always have access to the admin scripts to check the status of the components of the application and the database. In addition, you must have access to the log files.

  • Incorporation of a control "web view" in a native application

    Something I wanted to say to ask the NDK experts this week but I forgot: it is now possible to integrate a web browser in a native application, similar to how this can be done via a web control in Adobe AIR applications?

    Cascades is currently provided as part of the SDK BB10.  The plan announced publicly, is that BB10 will be available on the PlayBook sometime after that BB10 phones are released later this year.  I can't speculate on dates.

    And can't I speculate on the question of if the waterfalls will appear publicly in a version of the pre-BB10 PlayBook software.  We know only what is known

    I asked webview native non-Cascades and I was told that is not available today.

    See you soon,.

  • How can I fix windows 7 Catalyst control center host application has stopped working

    I received the error: Catalyst Control Centre: host application has stopped working. I uninstalled the Device Manager Catalyst Control Center and restarted - after uninstall and reboot I got the same message saying: Catalyst Control Center: the host application has stopped working - I also checked for driver updates in the Device Manager and the device manager says my driver updates are up-to-date.

    I just received a response from AMD for a known issue with Catalyst Control Center and Windows 7.  You can go there.  It worked for me the first time after a lot of troubleshooting.

    How to solve the CCC is not loading/opening at initialization.

    Scenario: the user tries to open/load the CCC through different methods, but it does not load. The problem may occur without any changes to the system or a Catalyst driver update or reinstall. This is issue mainly affects Windows 7 machines.

    Cause: possible corruption of the Windows Global Assembly Cache (GAC). Usually, this requires the user to format and reinstall Windows.

    Resolution: this solution has been tested - reproduced and resolved.

    Remove all the ATI through programs and features in Control Panel using the Manager to install Catalyst (GPC). Restart the system in safe mode and follow these steps:

    -Remove all ATI C:\programs files files and the C:\programs files (x 86)

    -Go to the C:\Windows\assembly and sort by "public key token. Locate the following key token public "90ba9c70f846762e" which is

    -associated with ATI. Usually only 2 entries. Remove 2 entries. Note: entries should be deleted (right click and select uninstall) since regular safe mode

    -mode may cause a permissions error. 2 entries appear only in the systems concerned by this issue. This means that you want the 2 inputs on systems where the CCC charges, the entries do not exist.

    -Close and restart normally.

    -Reinstall the ATI Catalyst package.

    I hope that you will get in working order!

  • Flex help control list

    First of all, Hello! I have (like yesterday) downloaded the demo of Flex and started messing around. The first thing I wanted to do was a small file download utility that I've done... but there is a bug that I can't solve. It involves the list control. In my application, you drag the files from the Office on a list control that shows then all the file names that you want to download.

    Everything works well except if you drag files enough on the list control to scroll. Once you start to scroll, it seems that the data becomes just borked and I see the same file name, repeated several times and other file names seem to disappear. I was hoping that someone could take a look at the code below and see if they can spot the problem. Please keep in mind, this is my first experience with Flex and I'm not entirely sure that I use the control and the dataprovider stuff properly!

    I do not still air, but I don't know that table low-level methods, as 'push' ship no events necessary for correctly updating the user interface.

    You must use an ArrayCollection for the List.dataProvider collection, not table and use the ArrayCollection collection API to manage updates. (addItem(), etc..)
