How to set the number of visible items in the drop-down list
How can I specify the number of elements is visible in the list when I open a drop-down list? By default, I see 5 items, but I want to extend that to 10.
Reference doc: http://www.blackberry.com/developers/docs/airapi/1.0.0/qnx/ui/listClasses/DropDown.html
for example
var dd:DropDown = new DropDown();
DD.x = x;
DD.y = y;
dd.rowCount = 10 ; Set this value to the need... like for example 10
CDI Width = w;
CDI Height = h;

How to use the drop-down list box to fill in a text box
I'm a beginner when it comes to Java Script. I have seen a lot of different discussions, look at a lot of articles "helping" Acrobat 9 and Java Script, but only to be left confused and dazed. I hope someone can tell me how to write a script that fills a text box that sits on my form with the value of exports of the selection in the combo box...
Thank you
If you want that the read-only text box, simply set with the following custom calculate script:
Set this field to the value of the drop-down list box
Event.Value = getField("combo1").value;
but replace "combo1' with the actual name of the combo box field.
If you want something else, post again with more information.

How to fill the drop-down list components installed?
I have installed Eclipse and the blackberry for eclipse plugin that includes the component pack 4.5.0. I have installed all of the components listed on this page: http://na.blackberry.com/eng/developers/javaappdev/javaeclipseplug.jsp. The versions 4.2.1 and 4.3.0 are zip files that I add to Eclipse by using the software update-> add the site-> archive. Version 4.6.0 and 4.6.1 4.7.0 are exe files that settle in the location C:\Program Research In Motion\BlackBerry JDE component Package 4.x.x.
In the folder plugins on the box, I see version 4.3.0 and listed 4.5.0 4.2.1. When I go on Blackberry JDE-> installed components and click the drop-down list box, the only pack component that I see is 4.5.0. How do the other components packs appear?
Well it's resolved, I guess. After about 3 hours, the software updates-> add the site-> repository for the Blackberry update works. When I installed the components as a result, they appear in the drop-down list. It's a little confusing, because I already tried this at least 5 times and each time before eclipse was a java error when doing this.

When you change the layout of a document in some way, you must save the PDF in dynamic PDF. Your currently saved him in the designer as a static pdf that's why nothing happens. Just do a file-> save as and select Dynamic PDF from the list. When you preview it the next time it will be set dynamic pdf.

Hello
You can create the same drop-down list using the ToolTip Widget composition but the only way that you can add on turnover and deployment will be discoloration.
Please check the attached file. http://adobe.ly/1IxxKfO
Another alternative is to create a lively border animation and use it in Muse as a file OAM.

How to hide the drop-down list of the Chat pane
Hello
I had provided that I don't want the combobox associated the SimpleChat component and the text "user typing" is anyway to hide those. ?
Hello
My advice for your case would be to build your own simpleChat UI with the simpleChatModel that we provide and you can have the freedom to do whatever the desired user interface. Our example of SimpleChat folder samepleApps built a UI using the SimpleChatModel cat.
However, if you feel to follow the path of quick fix, you can simply override the createChildren() or other functions in your subclass of CustomSimpleChat of SimpleChat and use only visible/hide no matter which component. You can look at the source code for player 9 in SimpleChat for more details. Its useful as a reference in many cases the same if you use Player 10 swc.
For your specific case, you can do this in your subclass
Override protected function createChildren() (): void
{
super.createChildren ();
{if (_toCombo)}
_toCombo.visible = false; to make the invisible combobox
}
}
Override protected function commitProperties (): void
{
super.commitProperties ();
If {(_typingLabel)
_typingLabel.visible = false; to make typing invisible label
}
}
Thank you

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); -

You can choose several items in a drop-down list?
I was asked if it is possible to make a drop-down list in which two elements could be selected? (as you want to choose colors gray and blue) Or it is limited to one per drop of water down)
If so, how to set the drop-down for this button?
I'm a newbie, be gentle. Thank you.
No, it is not possible with a drop-down list. You can do this by using a list box
field, however.
