Beginner problem Qt - signal clicked() button does not

Hi guys,.

I'm sorry to waste time of people with this problem, but it was my * beep * for a while and I really cannot proceed without assistance.

Basically, I just try to hang a signal clicked() by a button. I've got the button instance, but the connect call returns false and the slot is not called when I click on the button.

Here is the code:

Class ApplicationUI: public QObject
{
Q_OBJECT
public:
ApplicationUI (bb::cascades:Application * app);
Virtual ~ ApplicationUI() {}

void GetButtonClickHandler();

BB::Cascades:button * _getButton;
};

==========

ApplicationUI::ApplicationUI (bb::cascades:Application * app)
: QObject (app)
{
QmlDocument * qml = QmlDocument::create("asset:///main.qml").parent(this);
AbstractPane * root = qml->() createRootObject;
App-> setScene (root);

_getButton = root->findChild ("getButton");
Boolean result = QObject::connect (_getButton, SIGNAL (clicked ()), this, SLOT (GetButtonClickHandler ()));

_getButton-> setProperty ("text", "Yes");
}

Sub ApplicationUI::GetButtonClickHandler()
{
_getButton-> setProperty ("text", "clicked");
}

==========

Default empty project template
import bb.cascades 1.0

{Page}
{Of container

Button {}
objectName: "getButton.
text: 'Get '.
horizontalAlignment: P
}
}
}

Thank you very much!
Paul

Try adding:

public slots:

above this line:
void GetButtonClickHandler();

In addition, you can use the methods of the button directly, as
_getButton-> SetText ("clicked")

BTW, member variable is not really necessary. Slot sender() method can be used to access the button:

void ApplicationUI::GetButtonClickHandler(){  Button *button = qobject_cast

  • Shortened on Quiz submit make sure you "click" button does not work! CP8 - HELP

    Can someone help me out here?

    Well, I have a few quiz questions. If I don't have a shortcut on the button submit, it works fine. If I put 'Enter' on the button submit, I can't click on it. Yes, allow mouse clicks is checked.

    I wish that my users to be able to press enter or click.

    Thank you for any insight gang,

    Looks like I was victim of the transparent button again.  When I pass the quiz buttons to text or image, shortcuts on them work very well. Then they are transparent I have problems.  The nice thing about transparent, it's that you can color. Because you cannot use smartshapes as real quiz buttons (send, etc.) at least not that I know, I had to place a smart shape on the masterslide and overlay a text with 'make transparent' button selected on the top to make my buttons look AND behave properly. Adobe is now aware of the issue.

  • My mute button does not work

    The button does not work everytime I try to put my phone on silent. I turn it down and it will automatically return to the sound, it activates again upward. What can I do?

    Hello Jackie101foever,

    Thank you for using communities Support from Apple!

    As I understand it, you can't silence your iPhone.  I have a suggestion that should help you with this.

    The first thing we want to do is to make sure that you have a current backup of everything on your iPhone.  If you follow this link, you will find instructions on how to make a backup:

    The backup of your iPhone, iPad and iPod touch

    If the silent button moves upward on its own, so you must do this checked by a service representative.  You can find the nearest one by looking here:

    Find locations

    If the button is stay down, but do not silence the iPhone then we want to restore all settings.

    Reset preference files resets all parameters that may be problems. This step will not delete your contacts, photos or personal information. It deletes all your preferences for Wi - Fi, Bluetooth, do not disturb, Notifications, general, sounds, brightness & wallpaper and privacy and removes your Touch ID & password.

    Do you this by clicking on settings > general > reset > reset all settings.

    Once you have done this, restart the iPhone and see if you are able to turn off the sound.

    Have a great day!

  • Firefox automatically updated itself, would not add new bookmarks, then deleted all mine, will not always add new, now the back button does not work. I'm Livid.

    I think I'm on Firefox 13.0. He put itself as part of the update of my computer up to date (at least I guess that's what happened, because it has changed). I noticed yesterday that he would not favorite Web sites, but I thought it was just the website or bookmarks have been full-time or something. Today, I tried to remove a few bookmarks to make more, but they would not remove. I tried to register a new site, and it wouldn't work. I tried to close/exit firefox and re-opening of the program. While the program was closed, I installed the next set of updates on my computer. When I have opened firefox, all my favorites, and the tab menu (or what you call personal small bar on the actual tabs) were gone. I can't always favorite of new sites, so I can't even re-do all my favorites (and I got a lot, all of them arranged so it's a big loss and incredibly annoying). Then I realized that the back button does not work. And the cursor remains on the typing that I symbol, it does not change the arrow, when I click on a link.

    One possible cause is a problem with the places.sqlite file that stores the bookmarks and history.

  • "Back" button does not work with the latest version of any help?

    Hi, I use the latest version. When I go through the pages, I can not be able to return to previous pages. The back button does not work. When I click the back button, the same page, it's not coming back... Any help would be much appreciated!

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

    You can click right back or front button to open the history list.

    You can hold down the left button of the mouse either back or next to the history tab list opens.

    The current active entry has a bullet in front of it.



    If you place an entry in the historic session with the mouse tab, so you see an arrow to the left pointing (rear) left or right (forward) to show the direction.

    You can left click on an item to open it in the tab active or middle-click or Ctrl, click on an entry in this list to open that link in a new tab, just as you can with the other links.

  • Home page button does not, how to fix?

    In my Firefox 4, the home button does not take me to the homepage. However, it opens a blank page saying browser.startup.homepage = about: home and the address "chrome://branding/locale/browserconfig.properties" appears in the url bar.

    I tried fixing it by clicking on restore by default and it still does not work.

    Any help appreciated.

    I would hazard a guess that you have some installed plugin which changes the settings of Firefox. Try safe mode, and also look at what is stated in your Windows XP lists as installed programs.
