• How can we change the visibility of the drop-down list after its creation?

  I create a QML document with three drop-down lists.  Depending on how "trans_type" is selected, only to drop Extra should be displayed.  If the option "account" is selected, the drop-down list is visible and the DD category is hidden.  The reverse is true if the 'category' option is selected.

  Here's how I build my QML document:

  void Testing::updateFields()
  {
      if (m_form.isNull())
          return;
  
      // Clear all fields from the form
      m_form->removeAll();
  
      // Clear the internal mapping
      m_fields.clear();
  
      //get the transaction page ready
      QmlDocument *qml = QmlDocument::create("asset:///transaction.qml").parent(this);
  
      DropDown* trans_type = qml->createRootObject();
      trans_type = DropDown::create().title("Transaction Type");
      trans_type->add(Option::create().text("Accounts").value("0"));
      trans_type->add(Option::create().text("Categories").value("1"));
      trans_type->setSelectedIndex(0);
      connect(trans_type, SIGNAL(selectedIndexChanged (int)), this, SLOT(onDDChange(int)));
      m_form->add(trans_type);
  
      DropDown* account_dd = qml->createRootObject();
      account_dd = DropDown::create().title("Account");
      account_dd->add(Option::create().text("No Account").value("0"));
      //... code to populate account drop down here...
      account_dd->setSelectedIndex(0);
      m_form->add(account_dd);
  
      DropDown* category_dd = qml->createRootObject();
      category_dd = DropDown::create().title("Category").visible(false);
      category_dd->add(Option::create().text("No Category").value("0"));
      //... code to populate category drop down here...
      category_dd->setSelectedIndex(0);
      m_form->add(category_dd);
  
  }
  

  Everything is displayed properly on the page.  onDDChange is called and it shows a Toast that the option has been selected.  Here is what I currently have in onDDChange:

  void Testing::onDDChange(const int &info)
  {
      QString msg = "Switched To: ";
      if(info == 0) {
          msg = msg + "Account";
      } else if(info==1) {
          msg = msg + "Category";
      } else {
          msg = msg + "Unrecognized";
      }
      showToast(msg);
  }
  

  I can't figure out how to get the drop down lists to be visible/hidden depending on the needs.  There is a function "setVisible()" for the drop, but I can not understand how to operate without the app crashing.  http://developer.BlackBerry.com/Cascades/reference/bb__cascades__dropdown.html#function-setVisible-v...

  My questions are:

  1. How can I change the visibility of the appropriate dropdown lists in a different function when the status of the main drop-down list is changed?

  2. is there a way to define an id for drop-down lists?  If not, how am I supposed to go into the drop-down lists in a variable later so I can receive their value or change the visibility?

  Any help would be great.  I've been struggling with this for a while.

  There are a number of methods you could use signals and slots between your code and the QML or something simple is assign "objectName" as a property, then this search in C++.

  http://developer.BlackBerry.com/Cascades/documentation/dev/integrating_cpp_qml/

  Something like

  DropBox db = mRootContainer->findChild("dropboxname");
  db->setVisible(true);

I specifically put by default in the settings option and figure that he took over the top NOT the default. This question never used to cultures upward, but since a recent update for Thunderbird, he chooses the top of the list only Preferred not on the list.

  Note that the name of the folder and the name are case-sensitive. It must be userChrome.css and it must be placed in a folder named chrome.

  The inability to drag or move a button usually means that you have opened the pane customization evil.

• Response of local folders looks like the answer to the discussion group. No signature or formatting options. How can I change the local folders meets regularly?

  Please see image attached. Responses from the eyes of local folders as responses to the discussion groups. No signature or formatting options. How can I change the local folders meets regularly, as they are in the Inbox?

  I don't think that the format of replies to the messages in the local folders are linked with focus groups or to individual account settings. As local folders can contain messages between several accounts or identities, it is more likely that formatting uses the setting of the account or identity appearing in the: field when you reply.

  This is how I think it should work. How this works in practice may be different.

  The new tab in Firefox 33 zoom is too high to see all 12 of my thumb nail. I changed it using ctrl - but the next time I opened a new tab, the zoom is 100%. How can I change the default zoom for the new tab only?

  I posted a style rule to shrink the tiles, which allows several of them on the page, but naturally reduces their legibility. You can experiment with the dimensions to find a look that works for you.

  https://userstyles.org/styles/106326/shrink-new-tab-thumbnails

  I use the Stylish extension to experiment because of its preview function that allows me to see the effect quickly. You can install it from the site of modules, then after restart of Firefox while searching for his "S" icon in the toolbar to manage Styles so you can edit and experiment.

• I changed my password of gmail e-mail. How can I change the password used by Thunderbird to connect to gmail.

  I changed the password used to access my gmail account. Thunderbird still uses the old password to access the account. How can I change the password that is using Thunderbird. The last time this happened I ended up creating a new account to Thunderbird for gmail. Create the new Thunderbird account at least let me enter the new password. I don't really want to have three accounts of Thunderbird for the same gmail account.

  Please do not respond with suggestions on using password manager. I do not use it and do not want to start. I looked, and none of my Thunderbird passwords are displayed here. All I want to do is change the password in Thunderbird. If Thunderbird does not have a feature that allows you to change passwords, should be added.

  The link posted by Christ1 gives WRONG directions. In Thunderbird 24.4.0, is:
  Tools, Options, security, passwords, saved passwords

  Admittedly, in fact, you want that he SHOWS you the passwords, and then you can delete them.
  Once fact you check for mail, it will tell you, it didn't, and then you have the option to enter a new password.
  MUCH too complicated. Time to put the password and the ability to change, in the e-mail account options.
