ListView with GridListLayout will not display items

I can easily create a ListView that displays its items.

The following XML code:

And here's the QML:

            ListView {
                dataModel: XmlDataModel {
                    source: "asset:///test.xml"
                }

                listItemComponents: [
                    ListItemComponent {
                        type: "header"
                        Header {
                            title: ListItemData.title
                        }
                    },
                    ListItemComponent {
                        type: "item"
                        Label {
                            text: ListItemData.name
                        }
                    }
                ]
            }

The result looks like this:

But what I really want are the items to display in a grid. To do this, I put the ListView layout property to a GridListLayout:

                layout: GridListLayout {
                }

When I do that, it shows more elements, only the headers:

What I am doing wrong?

In the end I tried to get this working using a custom LitemItemProvider that uses images for the elements, but even once, it would display only the headers. So I simplified my example as much as I can above to try to identify the problem. I don't know how to do the simple example. I am able to get my original code works fine even with the GridListLayout if I do not activate the grouping - as soon as I activate the grouping (so that the data has headers and elements), it starts to behave like that.

The display of the grid is not compatible with the Group? The application of native images only grouping with a grid view, and I am trying to imitate that. Super confused.

You must set headerMode

Firefox will not display on the screen even though with Process Explorer, I see active Firefox.exe but no CPU usage

I use Firefox as default browser v10.0.2 on Dell XPS8300 Intel Core i5 and Windows 7 Ultimate and Compaq Presario CQ57 IO IO Intel Core i3 and Windows 7 Home. More frequently on the (approximately 90% of attempts) that Dell (50% of attempts) Firefox will not display on the screen when I click the icon. Cannot display other programs when it happens. I expressly say display because I believe that Firefox has started. To work around the problem, I installed Process Explorer on both machines and launch this program first, then click on the Firefox icon. When the problem occurs I see process Firefox.exe in the list of processes; some CPU consumed but, then, no CPU activity. If I click on the Firefox icon, yet another process opens in the list of processes, but with the same answer - some consumed CPU and then no CPU activity. If I have 2 processes running and kill the process from the 1st, the 2nd poster and then everything is normal. If I do not open it treat a 2nd, but kill the 1st process then click the Firefox Firefox is displayed and all then is normal. This problem has occurred since the original on the two new machines installation. I have updated the video drivers on both computers.

OK, let's see if we can solve this problem and make it work for you!

First of all, if you start Firefox in safe mode (restart your computer first, then when you open Firefox, hold down the SHIFT key) it starts more reliable? This is usually caused by a defective module. If this does not help, then restart Firefox, go to the Firefox, then add-ons button and disable your extensions one by one until you find the troublemaker.

Also, try to update to Firefox 11, it has several bug fixes that might make life easier here.

Just as a few troubleshooting steps base to ensure that we have all the bases covered,

"Non-rectangular objects will not display correctly when you export with the help of CSS."

I use Ind CC 2014 export a document to an epub recomposable. The document contains a picture .ai. The image export correctly in some parts of the the.epub, but not others, when it is deformed. There is a warning on export: "Non-rectangular objects will not display correctly when you export using CSS." Any suggestion is appreciated.

Hello

For these objects, the best option is to 'rasterize container"to preserve appearance of the page layout setting in the Options of the Export Object dialog box and then export to EPUB recomposable.

Kind regards

Hi @WoodyJr9,

Welcome to the Forums of HP Support!

I understand that you are having problems with your screen either vacuum or go to sleep after a few seconds. I'm happy to help you with this.

Please see the following, because it can be the starting point with the problem you mention.

If this does not help, then take a look at these:

Another thing you can try is updating drivers, if you don't have already done.

Vista will not display description of the file on mouse over. File name, Type, size, and Date modified see the upward, but no description.

Vista will not display description of the file on mouse over. When I mouse over, a pop-up window displays showing: file name, Type, size and Date of change, however, it does not show the description of the file.

So, for example if I have 5 files on different types of screw - the description tells me that the size of the screws. IE. 1.5 mm or 1. 8 mm.

Update: try to get the description of the file displayed messing around in the file properties, now out of 10 records, only 2 includes the name of the file in the mice on the pop-up window. So now what lack us, it's the file name and the Description file.
Help, please...

Description of the file in as long as this is not one of the available variables, which can be shown with ToolTips - but there are others who could easily serve the same purpose. Here are the options:

Photoshop CC 2015 will not display the RAW files

I installed Photoshop on my new computer and it will not display the RAW file when I go to change. Instead, it shows a rectangle cream colored with a dark blue background. If I click Open a picture, it will open it for further editing and I can see the image once again, but it will not display in the initial screen. I have version 9.4 of the camera RAW plugin and the computer is a HP Envy with Windows 10 if that helps. See screenshot for reference.
Can someone tell me how to solve this problem?

Will not display labels accordions - SECOND POST
Hi all

When I create a SWF with a part of the accordion, it works fine. When I import the swf in another film will not display labels. I also tried resetting the label using myAccordion.getHeaderAt (index) .label = "Blah"; or createChild(); without success.

Am I missing something fundamental?

Dave
I finally found the problem with this - I load me the film in a container element that has been hidden. I pulled it out of the mask group and it worked fine.

Thanks for your help Urami :-)

Indeed, it looks like a serious hardware problem possibly motherboard or maybe the CPU what to say to solve this problem, you must replace the parts and it will be a costly affair if the guarantee is not valid.

My laptop Sony VAIO with Vista will not connect and stay connected to my wireless internet. All other laptops in the House are perfectly. Internet disconnects, says local only, then reconnects constantly making internet hard work.

Hi Tinkerbellfancolorado,
1. When is this last work fine?
2. Do you receive an error message or error codes?
3. Recent changes on the computer?
There could be several causes for this problem.

Try starting with these methods.

Method 1

Step 1
1. Open Network Diagnostics by right-clicking the network icon in the notification area, and then click diagnose and repair.
2. Make sure that all cables are connected (for example, make sure that your modem is connected to a working jack or cable phone connection, either directly or through a router).
3. Reset your modem and router. Remove the power cord from the modem or router, wait at least 10 seconds, then plug in the modem and/or router back.
Step 2

Another reason may be windows disable your network adapter to save power. Turn off the power saving option in the properties of the network (wired network only cards) card:
1. Open network connections by clicking the Start button, clicking Control Panel, clicking network and Internet, click network and sharing Center, and then clicking manage network connections.
2. Right-click on the connection and then click Properties. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
3. On the Networking tab, click Configure.
4. On the power management tab, clear the allow the computer to turn off this device to save power option, and then click OK.

Method 2

Temporarily disable the firewall, and check the status.

NOTE: To re-enable the firewall after check you the status. If you are connected to the Internet or a network during the time that your /firewall antivirus software is disabled, your computer is vulnerable to attacks.
