Dynamically add tabs QML from C++
Hello world
I have a simple TabbedPane defined in QML. I am trying to reference the TabbedPane via C++ to dynamically add tabs. Is this possible? With my current setup, the application starts and crashes then with:
Process 22253787 (MyTabsApplication) terminated SIGSEGV code=1 fltno=11 ip=79310524(/base/usr/lib/libbbcascades.so.1@_ZN2bb8cascades10TabbedPane6removeEPNS0_3TabE+0xf3) mapaddr=00110524. ref=00000010
Here is the code:
TabbedPane {
id: mytabs
objectName: "mytabs"
Tab {
title: "Tab 1"
FirstPageView {}
}
showTabsOnActionBar: false
}
C++ :
ApplicationUI::ApplicationUI(bb::cascades::Application *app) :
QObject(app) {
QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);
qml->setContextProperty("app", this);
AbstractPane *root = qml->createRootObject();
TabbedPane *tabbedPane = root->findChild("mytabs");
Page* page = Page::create();
Tab* tab = Tab::create()
.title("tab2")
.description("This is only shown in the side bar");
tab->setContent(page);
tabbedPane->add(tab);
app->setScene(root);
}
Thank you!
Try to declare your root as:
TabbedPane *tabbedPane = qml->createRootObject();
As TabbedPane is a class of AbstractPane

Dynamically add controls
Is there an example of how you can add controls dynamically in code
I have an ObjectChoiceField with a listener and I need to add and remove controls dynamically depending on the choice.
using Java Plugin Eclips
970
Welcome to the forums.
No need for samples, all you have to do is 'Add' in the same way that you do when you add the original controls to the screen. You can remove. The trick is that you must be running on the event to do this Thread, but if you do this in a fieldChangeListener or a click menu or change of focus, then you run on the thread of events and add/remove operations is possible.
Hope this is enough Info for you.

Add control click and move click functions.
In design mode, I'd like to be able to order click or shift click on the images in slideshow lightbox Muse so that I can select and delete several images at once. It is a real pain when you need to delete 70 or 80 one-at-a-time images. Is this possible?
Select a thumbnail, do a select all and press DELETE. An image will remain, which is annoying, but the way it works right now. You can also use shift + click to select several thumbnails and then click on remove.

How we can dynamically add or remove action from the popup menu in qml item
Hi all
I want to just dynamically add or remove action from the actionset item in the contextual menu especially in qml.
Thanks in advance.
Kind regards
Ankur
You can do so by joining the actionitem as attachedObjects. Once the page is complete (signal onCreationCompleted), you can add it to the page using addAction()
To remove, you simply delete the page using removeAction()

Handling dynamically created components qml in C++
Hey,.
I dynamically create a qml page by using the following code:
onClicked: {
var favPage = favPageDef.createObject();
nav.push(favPage);
}
attachedObjects: ComponentDefinition {
id: favPageDef
source: "FavPage.qml"
}
I would now like to manipulate the components in this new page qml in c ++. How to access these components?
I was able to access the qml components fairly easily if they were created during the initialization of the application, but of course, this isn't the case.
I discovered what the problem was. I had to do my public AbsractPane in my header file. Then when I created the qml component and calls a function in c ++ it turns out to be a child. Thanks for everyone help well.

How to dynamically add data in a Spark list control
Hi, I have a spark list in one of my custom components() control(id="Cclist") and a text input control. When a value is entered in the entry of the texts, I want to dynamically add the same in the list control. I tried to do the following:
protected function Cc_selectHandler(event:CustomEvent):void
{
var cctext:DisplayObject = event.data as DisplayObject
CcList.enabled = true;
CcListButton.enabled = true;
CcList.addChild(cctext);
}
But I get an error saying "addChild() is not available in this category. "Instead, use addElement(), or change the skin. So I tried to use addElement, but apparently it is not available at all. No idea what im doing wrong?
Add the text entered in the textinput to the dataProvider of the list in the appropriate format.
A simple example:

How to dynamically add any control (digital button, boolean) to control the line and selected column
Hello
How to add a control (digital button, boolean) dynamically in control instead of lines and columns selected. Please suggest the idea or no matter what example code you have please share with me...
Thank you
Vieu
Essentially, that's what you're looking for:
Please note that you have to account border sizes and the label of the control so that the code does not work right out of the box. You should also check for the height and width of column and if the position is valid at all before moving around the control.

Dynamically add custom headers in ListView
I'm working with a ListView which is based on a api, that I have no control.
I dynamically add some custom headers subject see the following as to what I am referring to (A, B)
http://developer.BlackBerry.com/native/reference/Cascades/bb__cascades__listview.html
How can I dynamically add these? For example, I want to add a conflict between the first element of the list and the second
Section A
Header
Item B
Point C
Hi Philippe,.
To do this, you must use a custom list item component.
Heres how I could do that
Moreover, in the custom "Header" just create a structure as follows:
IF/ELSE ON A FLAG
if(someflag == "header"){
//use header style
}else{
// show normal list style
}
My Code
ListView{
dataModel: ArrayDataModel{
id: myDataModel
}
listItemComponents: ListItemComponent
{
Container{
layout: StackLayout{
orientation: LayoutOrientation.TopToBottom
}
Label{
text: ListItemData // complete data string
}
Label{
text: ListItemData.split("~")[0]
}
Label{
text: ListItemData.split("~")[1]
}
Label{
text: ListItemData.split("~")[2]
}
}//end Container
}//end ListItemComponent
onCreationCompleted: {
//The data inside append is one item.
//let's append a bunch of data
for(var i=0;i<30;i++){
//append 30 list items
myDataModel.append("Header~Some data whatever~Status");
}
}
}
- In my example I am adding data to the model.
ListItemData - the full string
ListItemData.split("~") [0] - first part etc.
- I shared parts of the data with a single symbol. In my case the «~»
- To get the data I want to that I just throw a ListItemData.split("~"). It breaks the string into 3 parts.
- I will be able to access somewhere I want using the notation ListItemData.split("~") [index]
- You can include paths to images, or whatever the text you
AS IF THIS HELPED YOU!

Allow users to dynamically add rows
Hello
During the creation of form, I found an option "allow users to dynamically add rows. I need so that users must be able to create new lines if necessary for new TBHs. How does this option, could someone let me know?
Thank you
IDI Hello
If the user has write access to the form and the option is selected to "Allow users to dynamically add lines", when the user runs the form that it has the option in the menu (Edit > Add Row)
Then, this will open a window where the user can select the members for the dimension of the row to which it has access.
The function does not work if you have selected "remove Missing Data".
Useful, correct, answered? you know that you can do.
See you soon

How to dynamically add a plot to a graph of mixed signals
I have a graph of mixed signals where I'm plotting a signal from a time axis. I'm trying to dynamically add a second plot to this graph against the same time axis (with a different scale of Y), but when I built a 2D array and try to connect in the graph (using a local variable) I get an error of size mismatch. I know for sure I did in the past (cable tables with different sizes for a same MSG) with no problems but, today, for some reason any I can't solve this problem.
Am I missing something?
Yes, you're probably writing a table 1 d somewhere that is causing to accept only 1 d. To address your problem above, just put a table node build in whenever you have a 1 d table and it will be just a 2D array with a single line of data.
To add a field to your current locations, your screenshot above should work once the plot knows that he has to accept the 2D tables.
Reading from a local variable, change something and then write about it once again can lead to a lot of issues down the line. Race conditions are a pain in the butt, so get rid of that sort of thing is good to do from the start. I didn't know the rest of your code, so I don't know how you treat it, but just keep in mind that you add to your software.

REALLY disturbing dynamic sound control
I bought a HP ENVY 17 Notebook PC in September 2012 and I really like it! Wonderful machine, releasing my creativity... Well, not really. I listen to music when working, but there is this terrible dynamic volume control. It cut spikes and stimulates the troughs, which I'm not interested. Or at least try that. Indeed, there is a delay to that effect, so that the adjustments are happening a little too late. In addition, the paler parts are completely reset to zero, probably because white noise dominates the picture. Maybe it's a good idea for children playing games and watching action movies, but he certainly isn't a good idea when you are listening to classical music. What can we do about it? I haven't used my CD equipment for ten years, I've eventually there again? Turning off beatsaudio does not help. The following patch help for HP ENVY? FTP://FTP.HP.com/pub/SoftPaq/sp57501-58000/sp57966.html , please help me! I can't go on like this any more!
If you have not already, I download and install this hotfix. It should help to solve the problems you are having.

How to dynamically add an Option in the drop-down list?
I have this code:
{Drop-down list
ID: list
Title: 'list '.
onCreationCompleted: {}
opion var = new Option();
opion. Text = "Hello";
opion. Value = 4;
List.Add (opion);
}
}
After the launch of the application, the list is empty.
Why my code does not work?
It is easy to dynamically add options
first add this to your attachedObjects:
ComponentDefinition {
id: optionDefinition
Option {
}
}
then do something like this
var newOption = optionDefinition.createObject()
newOption.text = ...
newOption.value = ...
newOption.description = ...
newOption.selected = ....
yourDropDown.add(newOption)

Dynamic add to cart
Hey everybody, just try to see if there's a way dynamically add something to the cart. I see the html code for how works the add to Cart button, but it looks like it uses the ID 'product' to add the product itself. However, I am not able to see how I can retrieve the id of the product if all I have is the 'Product Code' (from {tag_productcode}). These two values are different for non insiders.
I know that if I work a little longer on that I could just get some ajax to visit the real great product page manually and find add to Cart button and enter the ID of the product in this way, this seems excessive.
If anyone has any ideas, I would be very grateful.
With the add to Cart then that.
I don't know why people do not use the documentation - all that it:
The developer reference
{{id}}
|
{tag_productid}
|
System displays product ID. |
{{catalogId}}
|
{tag_catalogueid}
|
These two you will need dynamic, but make sure you also get the other correct settings.
