Is that possible to do such things with ag-grid?
Thanks in advance.

I have some existing code that renders Antd 3.x Tree. It uses lot of Tree props to manage the expand and collapse. Now I would like to show each Node(all nodes) separated by a line(to look similar to a Table) so all nodes are separated row wise. If I try to style "TreeNode", it obviously only applies to the node and since the arrangement of parent-child node is relative, it doesn't look like a table(row separated). please advice. TIA
Please see the link
My last option would be to switch from Tree to Table with Children
I would like to add a frame to my menu so I could use border radius, but I do not want to derive the frame background color from the definition of my panels.
As I see it now the frame can only be defined on the panel level and the menu inherits this definition.
Can it be done?
The way you handle these is to use custom theme. ext-4.2.1-gpl/ext-4.2.1.883/docs/index.html#!/guide/theming will be help . It is in the extjs (sencha) SDK.

I Am from a WPF/XAML background and I'm trying to get my head into MVC. I am wondering if I want to create a data capture form, would you use table or div to structure the labels and dropdowns/textboxes etc.?
I ask because the template provided has all stacked one on top of another and wastes valuable screen area. I want to have my labels for Title, Forename, Surname all on one line/row and the same for data capture elements?
You should use div to structure your layout.
Also you can use some grid layout framework (like in Twiter Boostrap, see Grid system). If you have WPF background - it can simulate to some extent Grid panel from WPF in HTML world.
In HTML table tags should be used for Tabular data; layout of forms etc should be done using Div / Span tags for structure and CSS to control the structure.
Take a looks at the link below for input form structure example:

It's not only cleaner to use Div, but it also makes the page more accessible according to W3C rules.
I have a table view in PyQt that needs to have an image in every cell.
I have used delegation of a label (and added a pixmap to that label). But the problem is when I add 12 cells (12 images of size 60x30 pixels), the table becomes too slow, and I need to have a table that contains hundreds of images. Should I be using another delegation? Or is it just not doable with a table view? If so, what is the best widget for such a task?
Any answer for Qt or PyQt would be highly appreciated.
I think you should try using QGraphicsView for your purpose. Its much faster to render images on it.
One clever way to do is created a huge graphicsitem which mimics a table based on ur rows and columns count.
then add children graphicsrectitem item as each cell container.
lastly add the images as qgraphicspixmap item as children of the rectitem. this way u can make it quicker and also interactive since u can select them individually and also make them movable inside the cell by user by checking collision detection to make sure they are not pulled outside the cell boundary.
hope that provides u an alternative.
QListView provides an icon mode where you can stack your images in a grid.
I would like to animate a sequence of background images within a uicomponent but also dynamically add and remove components to this component.
My first question would be:
1.) What's the best way to animate a sequence of images using Flex 3?
2.) What's the best way to handle adding and removing components on top of the background dynamically?
Any help/information would greatly be appreciated!
Thank you!
In the mxml for your ui component declare an mx:Image and give it an id. Set up a timer loop that changes the "source" attribute (id.source = ) on your mx:Image at an interval you like. To add and remove components dynamically just use addChild/removeChild or addElement/removeElement depending on the type of display object you're working with. The mx:Image should always be behind the dynamically added components as it was created and added before them.
