I am trying to create a grid layout of images kind of like how google images does it.
I want to add fixed sized images left to right, top to bottom but I am having trouble is figuring out when adding another image to a row would make it not fit and then decide that that images should be placed in a new row.
Also when the window resizes it should move images into/from rows based on how many it can fit in.
Ive got a scroll area with a grid layout in it which is fine if I know what can fit, but I can't figure out how to make it move items if say the window width is shrunk, and say an item needs to be moved down 1 row which moves other etc.
Assuming you are using QWidgets I'd suggest you to use QListView which does the layouting for free, if you want more control on how items are displayed use a QItemDelegate. For QListView the view mode should be set to QListView::IconMode so that you have a grid of items and not a list.
But if you are using QtQuick things are much easier, a GridView with Image delegates would do what you want really quickly and using GPU power to build you UI.
In my air app I have a list(vertical) on the left side, like a sidebar. It`s working fine! The things is I want to put some animation in this list, which all the times when I select one item all the list moves, and this item goes to the center of the list!
Someone have same example or URL, or something?
Thanks!
I've done something similar using the AnimateProperty effect to animate the scrolling of a list to a given index.

I have main window and in this window I have QListWidget. I want this list to be central widget in the main window and I know that I can do that by writing code like setCentralWidget(QWidget*) and it works (list is spread on the whole mainwindow) but this isn't reflected in designer when the list is still in this same position and has the same size. Is there any way to make it so the change is visible in designer as well as in the code?
Thank you.
In Designer, right click on an area of the form next to the QListWidget, then choose Layout->Layout Horizontally (or vertically, almost anything is acceptable).
I figured it out. In order to do so I had to choose grid layout for main window and sizePolicy for list as Prefered.
I am trying to get a left hand like panel bar in my application, one much like the OneNote left hand(notebook) panel.
I have been trying to use a VBox with Buttons and setting the rotation on the buttons to 90. The buttons seem to disappear when I do this.
An example of what I am trying to achieve is here: http://www.rid00z.net/panelBarExample.png
What is the best way to achieve Vertically stacked buttons like this?
try putting all the buttons inside an Hbox and then setting the rotation of the Hbox to 90.
Oh and also make sure you rotate around using a point at the center.
I would create a custom component to do it. I would make each "button" a canvas and display text in it vertically (embedding the font you want to use to do that) - the canvas would have a click event - I would use canvas over a standard Button because it allows more flexibility. In this new component you would have functions to add or delete buttons. I can clarify if it would help.
To draw a "selection rectangle" from the mouse down , mouse move then remove it on mouse up i currently do the following:
My board is a canvas,
On mouse down i create a new UIcontainer i set his borders.
I update his width and height related the the mouse move position,
on mouse up i remove this child UIcontainer.
Do i have to create a new component for this kind of task or there is a better (lighter way) in flex ?
Thanks,
Here is an Flex selection rectangle example, although I think it won't be a better/lighter way, perhaps you can get some nice ideas from it.
I'd say you got it right.
