Created in the ListView lost when C++ ListItem custome context reference
Hi all
I have a listview that generates a list of the custome listviewItems (ie the containers). Containers have a setContextProperty to my database object. But when they are added to the list view, I can't access the database context property. I realize that the listview is not in the same context as the page but I don't understand why when I bind context for the real item the reference he lost?
Error: asset:///WorkoutListItem.qml:17: ReferenceError: can't find variable: _Dal
List.QML
Page { Container { ListView { id: workoutList horizontalAlignment: HorizontalAlignment.Fill dataModel: _Dal.ListofWorkouts listItemComponents: [ ListItemComponent { type: "item" WorkoutListItem { workoutId: ListItemData.id workoutName: ListItemData.name } } ] }//End List }//End root }//EndPage
WorkoutListItem.qml
Container { id:root property int workoutId: -1 property variant workoutName: "" layout: StackLayout { orientation: LayoutOrientation.LeftToRight } Button { id: workoutDelete text: "Delete" onClicked: { var result = _Dal.DeleteWorkout(root.workoutId) } } Label { id: workoutNumberLabel text: root.workoutId } Label { id: workoutNameLabel text: root.workoutName } Button { id: workoutEdit text: "Edit" onClicked: { //TODO: Open workout page } }}
application.cpp
QmlDocument *WorkoutListItem = QmlDocument::create("asset:///WorkoutListItem.qml").parent(this); WorkoutListItem->setContextProperty("_Dal", dal);
Thanks in advance for any help
-J
itemRoot.ListItem.view.yourFunction(ListItemData)
yourFunction (data) is defined in the ListView itself
from there, you have access to your context

Effect of color in the properties lost when used to break apart.
Flash CS5
How does one change graph then have the possibility to choose in the properties of color effects options such as alpha or luminosity or hue in properties?
Integrate a file .ai library and then creating a MovieClip of it, I can change alpha of the color or brightness or hue etc. in properties through the option of color effect. Use break hand to remove a simple box of a part of the work and just applied aspects of the color disappear, back to its original appearance. Try the work but still not grouping options now. It is even if I just place the image on stage or open the graphic in the library.
Try it out bring it a different way and to break, then alter the work group then to see if the properties has color effect option for this but still no joy.
Try to convert graphic after editing and giving it a new name, he Faints, nothing visible even if I select this chart in the library.
It seems that the only way to apply color effect in the properties of a chart or a MovieClip is NOT to change its content when placed on the stage. I can't do without needing to modify the program making the AI. In fact adds a box that I don't need, border of the page in this program.
Envirographics
Color effects can be applied to an instance of a movieClip or button or graphic symbol. When you separate an instance of movieClip, you actually spend this movieClip into its different parts, similar to the edition of the original symbol in the library. These parts, lines, and fills, no longer a movieClip, and so any changes applied to the movieClip will no longer apply.
You can select all the individual parts after your installation of these parts and then using the Edit menu, the value of this new group of lines and fills as a movieClip and reapply the color effect.
Alternatively, if you double-click on the movieClip on the stage, you will be in the editor. Any changes you make in the editor will be displayed in the movieClip when you return to the scene. The effect color will remain.

I upgraded my OS 9360 recently of OS 7.0 to v 7.1.0.336, 9.6.0.51 platform. Since the upgrade I have more the possibility to delete email messages on handheld only or on the server as well. I really enjoyed having the option to delete totally or just on my handheld and then discovered the mail later on my pc.
When I delete a mail from my BB, now, it just removes it from my device and the leash on the server without the option to remove it so. Can you please help me get this option back?
Kind regards
Stefan.Hello and welcome to the community!
Please see, on your BB, here:
- Home screen > Messages > > Options > email reconciliation
On this screen should be the ability to set the preference to "remove the ' back to 'ask '.
Good luck!

Focus of the app lost when VSStudio is open in win 7
I have a sign in application it's built in .net/Vs2010, when I run it on win 7 with firm... VSStudio app works very well that he steals the focus and works like a forground window... but as soon as I launch visual studio 2010, the leading feature no longer works thereafter. I tried even to change the registry setting to 0 for setforgroundlockedtimeout. but it works until the VS2010 is closed.
As soon as you open VS2010... win32 api call SetForegroundWindow() fails to keep the foreground window. There after if you shut up VS2010 always not behave in the way that it supposed to be. Let this work once again, I have to restart or logout m/c then app started working as expected, but if you open studio... Update loses automatically from my application for somehwere else.
Is plase advice the real culprit of VSStudio or something else?
Thanks in advance.

find the memory leak when switching from Teststand object reference to vi
I use Teststand to call labview vi and col ThisContext sequence to vi as object reference, but if I just completed this step and I can find the memory to help keep more, how can I avoid leaks memory inside the vi.
See my vi, is displaying an interface message user.
You should use a node reference close to close the references that you get after an invoke. In the code below, you should be able to close the references that you get the following:
AsPropertyObject
Thread
Close these two references, once you're done with them.
Also make sure you have turned off the collection of results of your sequence or you will use memory constantly to the results of the stage.
Hope this helps,

In the ListView docs, read carefully the section from "Visual list in QML", especially the parts on the ListItem.view and the surrounding things.
Basically, you need to do what you do indirectly through a property on the ListView and access via ListItem.view, or similar approaches.

Can you use the color picker when setting gradients in Illustrator?
I am able to set up a custom in Illustrator without any problem gradient, but I wanted to know if there is a way to use the color picker when setting your custom colors or if you are limited to a narrow bar of color (which has all the colors but feels harder to use for me)?
Click color to change in the Panel degraded stop / palette. Then, double-click on the fill area at the bottom of your tool palette/Panel. Who should bring up the color picker and color you choose apply until stop in the gradient you had clicked.
Alternatively, double-click the area fill with nothing selected to bring up the color picker. Choose your desired color, and then drag the color from the fill box to the Swatches palette/Panel to create a new shade. Later, with the gradient panel/palette active, you can drag samples directly on the steps of color to change your gradient.

All IT gurus out there who know Firefox... have lost the passwords saved when FF created a new profile and delete old files key3.dbf and logins.json profile. Any ideas, anyone?
So it's not a logins.json file?
I see a signons3.txt file and a file signons.sqlite older, if you can try to see if you can import passwords stored in this file.
You can force Firefox to re-import the passwords in the file signons.sqlite and regenerate the file logins.json with the following steps:
- reset the signon.importedFromSqlite pref on the topic: config page by default via the context menu
- Delete the logins.json file in the closed Firefox with Firefox profile folder
When you restart Firefox, then you should have the pref signon.importedFromSqlite with the value set to true.
You have passwords that are imported in the password manager, unless there were errors or signons.sqlite signons3.txt.You can open the topic: config page via the address bar.
You can accept the warning and click on "I'll be careful" to continue.You can use this button to go to the current Firefox profile folder:

Hello. Anyone know where to find my own predefined brushes created? I've lost all but about 5 of my own creations - but even those I don't think when I look in the backups... any ideas? I am a Mac user. Thank you very much in advance for any suggestions.
General Photoshop discussion !
I use Windows, and we need to make visible hidden files and folders in order to see the App data access path. OSX has a similar feature? If you have spent the hidden files and folders things, remember what I said about the registration of CC2015 the path of the CC2014 file. That one made me as well, but I worked it out by asking Photoshop to load new brushes and checked the place he was looking for.

How do I set the background / highlight on the listView when select multi use
Hi, I'm used to select multi on the list view, the problem is when the selected item does not change the background (I think by default will change in light blue)
Maybe because I'm not using StandardListItem on itemList, I use clean container for itemList.
How to set the color to the element highlighted on multi select listView?
Thank you
I use the background property on my customized itemList:
{Of container
ID: listItemContainer
background: listItemContainer.ListItem.selected? Color.Create("#18AFE2"): Color.create("#018AFE2")
...
}

audio of my video is lost when I import into windows live movie maker, but can be heard when played in media player. video is from jvc camcorder handy, file type is: MOD (video clip)

To access the values from the row outside the ListView ListItem
Hello
I spent two hours browsing the forums and documentation with no chance of finding a solution on how to access the list item data from outside the listview.
Let explain me my code. It is marked with I work and what does not work and its expected behavior.
Should work behavior
Tapping & getting dataThe arrayDataModel is filled with 4 rows. Firstly the list item, second item in the list... etc.
- Tapping on the order of the day, label with the id of triggeredText displays the value of a threaded list item.
- The index of the tapped icon appears in the label with the id of triggerredIndex.
Incrementing Index using ActionItems onBar
By pressing action items 'previous' and 'next', you can increment the index value to the label with the id of triggeredIndex. The order of the index is 0-4, even as total of the items in the list.
How to extract data from the index when the value of triggeredIndex?
Buttons
The buttons at the bottom of the screen... Select 1, select the 2nd, 3rd Select should select indexes 0,1,2 of the list and display the value in triggeredText and triggeredIndex. They do not work.
How did I pull the values when you click the buttons?
import bb.cascades 1.3 TabbedPane { id: root showTabsOnActionBar: false Tab { id: mainTab title: "Test List" Page { id: mainPage titleBar: TitleBar { title: "List Traversal Test" } actions: [ ActionItem { title: "Previous" ActionBar.placement: ActionBarPlacement.OnBar onTriggered: { // get current selected index from list= var currentIndex = parseInt(triggeredIndex.text); if(currentIndex <= 0){ //do nothing already at first item }else{ // subtract 1 from index ( ci - 1) ? var newIndex = parseInt(triggeredIndex.text) - 1; // show data from new selected index // ??? // triggeredItem.text = XXX // the data // ??? // triggeredIndex.text = X // the current index triggeredIndex.text = newIndex; } } }, ActionItem { title: "Next" ActionBar.placement: ActionBarPlacement.OnBar onTriggered: { // get current selected index from list= var currentIndex = parseInt(triggeredIndex.text); if(currentIndex == 4){ //do nothing already at lastitem }else{ // add 1 to index ( ci + 1) ? var newIndex = parseInt(triggeredIndex.text) + 1 // show data from new selected index // ??? // triggeredItem.text = XXX // the data // ??? // triggeredIndex.text = X // the current index triggeredIndex.text = newIndex; } } }, ActionItem { title: "Clear" ActionBar.placement: ActionBarPlacement.OnBar onTriggered: { // set current index to 0 (top item in list) } } ] Container { preferredHeight: maxHeight layout: StackLayout { orientation: LayoutOrientation.TopToBottom } Label{ id: triggeredItem // value of listitem from current index text: "0" } Label{ id: triggeredIndex // current index text: "0" onTextChanged: { // set triggeredItem.text to contents of selected ListItem with same index // STUCK HERE cannot access ListItem.dataModel(indexPath) from here.... } } Container{ ListView { id: theList objectName: "dalist" dataModel: ArrayDataModel { id: theListModel } listItemComponents: ListItemComponent { StandardListItem { id: itemRoot title: ListItemData } } onTriggered: { var si = dataModel.data(indexPath); triggeredItem.text = "LIST ITEM CONTENT: " + si; //set content when user taps on item triggeredIndex.text = "LIST ITEM INDEX INDEX: " + indexPath; // set index when user taps } onSelectionChanged: { //console.log(selected); } onCreationCompleted: { //add some data to the listview theListModel.append("First List Item"); theListModel.append("Second List Item"); theListModel.append("Third List Item"); theListModel.append("Fourth List Item"); } } } Container{ layout: StackLayout { orientation: LayoutOrientation.LeftToRight } Button{ text: "Select 1st" onClicked: { theList.clearSelection(); theList.select(0); } } Button{ text: "Select 2nd" onClicked: { theList.clearSelection(); theList.select(1); } } Button{ text: "Select 3rd item" onClicked: { //expected behaviour is to show data from Third List Item // triggeredIndex.text = INDEX 3 // triggeredText.text = (DATA FROM THIRD LIST ITEM) // THIS IS NOT WORKING .... theList.clearSelection(); theList.select(2); console.log(theList.dataModel(3)); triggeredItem.text = theListModel.dataModel(3); } } } } } }//tab }
Thank you and have a happy and healthy 2015!
Your help will be greatly appreciated.
I ran and got this:
asset:///main.qml:161: TypeError: Result of expression 'theList.dataModel' [bb::cascades::ArrayDataModel(0x1091a838)] is not a function.
But it works
theListModel.data([3])
But this isn't the solution, you have a more serious problem. You select a value, you trigger. If you add this in onTriggered you select it (and you can see that it changes color when it is selected).
theList.select(indexPath);
If you want to use option to deselect
theList.select(indexPath, !theList.isSelected(indexPath));
And if you want to have that one chose this
theList.clearSelection(); theList.select(indexPath);
Inside the button 'Select the 3rd point' allows to select programmatically
theList.select([2]);
It works but I'm not sure what you're trying to do

What signal is emitted in the ListView, when one of its cells appears in or from the screen turns off?
I created listView with custom listItemComponents
Is there any signal when listItemComponent go to the screen?
Currently, it is not possible to detect if the cells turns off the screen. Even if you join LayoutUpdateHandler them they will just stop send updates when you go off the screen. I managed to hack a solution using a timer, but I guess that a cleaner approach would more use a ScrollView with CustomControls instead:
1. get the dimensions of the ScrollView joining ScrollView LayoutUpdateHandler.
2. attach the LayoutUpdateHandlers to the CustomControls.
UPD: It is also viewableArea & viewableAreaChanged event scrollView property.
3. If the controls that were inside the visible area of the ScrollView went outside, raises the event.
Of course re-use of cell works that way.
It's so easy to grab the cell on the screen:
If you use ListItemProvider, updateItem() function is called when the element appears on the screen:
https://developer.BlackBerry.com/Cascades/reference/bb__cascades__listitemprovider.html
It will also be called if the data item are updated in the model.
When the item is created for the first time, createItem() is called.

Cannot create aliases form container in the listview
I tabpane wich call page of the listview. If a tab is trigerred the container property will change (as the background) based on the value I initialize in tab pane with alias:
But I can't create aliases to change the ListView:
Like this:
Page{ id: page property alias color: containerColor.background Container{ Listview{ listItemComponents: [ ListItemComponent { type: "item" Container { id: containerColor //other code } } ] } } }
What should I do?
Thank you.
Unlike ListItemData, ListItem is defined only for top-level ListItemComponent element. I think it should work:
ListItemComponent { type: "listItem" Container { id: topContainer // <----------- added line
...
background: topContainer.ListItem.view.getBackgroundColor()
