QML and Qt Quick

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.

[quote author="praneeth007" date="1406016204"]I want to modify those[/quote]You can't do that through signals and slots.

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.

Right. There are two different parenting concepts at play here: the first is the QObject (ownership) parent; the second is the QtQuick (scene / item) parent. Use setParentItem() to bring the item into the scene (by setting the item parent) and therefore make it visible.

Hi Dheerendra, Thanks a lot but still its not what i am trying to acheive. I am posting my code, please have a look. Here is the code and the problem i am facing with combobox options is, neither i am not able to get icons in my message dialog nor i dont know how i can see checkbox or line edit in message dialog, i am a beginner and struggling to explore the tricky ways used in QML. @import QtQuick 2.2 import QtQuick.Controls 1.2 import QtQuick.Dialogs 1.1 import QtQuick.Window 2.0 Item { id: root width: 580 height: 400 SystemPalette { id: palette } clip: true //!
