QML and Qt Quick

Hi, You could use "selection":http://qt-project.org/doc/qt-5/qml-qtquick-controls-tableview.html#selection-prop properties like select and deselect on ToolButton clicked.

I found a workaround by giving the tab an id and use @tabContacts.children[0].model = x.results;@ Nevertheless it would be nice that ids work also for tab children.

No i guess, last one will override.

Hi, thanks a lot that makes sense. I'll try that.

[quote author="p3c0" date="1406713166"]Hi, @ Rectangle { id: board width: 1000 height: 1000 color: "green" transform: Scale { id: scale; origin.x: 500; origin.y: 500 } } @ To use: @ scale.xScale += 0.1 scale.yScale += 0.1 @[/quote] The same behaviour. Try to zoom in (+) and drag the rectangle downright.

Hi, -For weather info you could use this API: http://www.worldweatheronline.com/free-weather-feed.aspx and show it in some labels. -For digital time: there's a widget in qt to do that, so you can get system time using QTime, and refreshing it using a Qtimer every second connected to an specific slot with your update routine. -For video: http://qt-project.org/doc/qt-5/multimedia-examples.html here you have a lot of examples.

These are exactly what I was looking for. I just found it in the documentation on repeaters also. Thanks! I ended up using the index like this: @Image { source: "button" + index + ".png" }@ because all my button images are buttonX.png.

You're Welcome :) You can mark the post as solved by editing and prepending the thread title with [Solved]

The file is actually created in a standard Data location of your system and that too inside the <your ApplicationName> folder. You can use "offlineStoragePath":http://qt-project.org/doc/qt-5/qqmlengine.html#offlineStoragePath-prop to get the path of DB.

@ Dheerendra what beemameni wants is not to superpose two images but to write the thumbnail version in the "meta-data" of the original image

hi the format of the image is mono_8 raw, because rosbag records in the format mono_8. I need another format to show the video in my qt gui, because qt cant visualize the format. I want to to convert from mono_8 to a rgb format

Hi, yes this is documented behaviour : The top postion of a flickable is defined by originY and this can be a negative number : check it out here : http://qt-project.org/doc/qt-5/qml-qtquick-flickable.html#originY-prop originX : real originY : real These properties hold the origin of the content. This value always refers to the top-left position of the content regardless of layout direction. This is usually (0,0), however ListView and GridView may have an arbitrary origin due to delegate size variation, or item insertion/removal outside the visible region. So you should use the originY value as the start position, instead of 0. OriginY can be negative, but should work fine as long as you take that into account in your calculations.

Is the image accessible outside Rectangle ? You can try to use Image element directly instead of placing inside the Rectangle. But i don't think so that would be a problem.

[quote author="Dheerendra" date="1406300961"]If you want QML object, that is the only way. If are not worried about QML, you can check QScriptable module for JavaScript and C++ integration. [/quote] Ok,I will try it.Thanks a lot~

Many thanks for the answers. I will try it and report.
