extjs 4 scroilling WITHOUT a scrollbar - extjs

I have this narrow panel which is basically a list of thumbnails, and i need to be able to scroll over them using buttons.
We have a panel (anchor layout), with containers in it, and each container contains the image.
there isn't space for a scrollbar, and anyway we don't want one.
I thought it would be as easy as in the listener for my button calling panel.getEL().scroll('b',20)
but this isn't working because the scrollHeight === ClientHeight so scroll does nothing.
Is there a technique I am missing or should this work?

So you're using a button to scroll through the images? What about having the button's listener remove/hide the containers/images at the front of the panel to allow the others to use the space?

Nested scrolling inside Swiper in react

I have a vertical swiper where in one of the slides I have a box with overflowing Y content, I want the user to be able to scroll vertically within the box. But in both dektop and android mousescroll is not working. No scroll event is generating from within the box, and scroll is interpreted as swiping. I also have a multiline text field inside same slide but I am able to scroll in that, so it must be possible. How can I make it work the way I want to?

Tab panel with items that don't fit the width of the panel

I am facing an issue where the tabs don't fit the entire width of the panel, and the user has to scroll to the right to view the rightmost tabs.
To see what I mean, please can go to this Sencha example, add enough tabs to enable the scrolling in the tab header.
My questions:
Is there a way to make the tabs wrap rather than having the scrolling effect?
Is there a plugin that can be used to create a dropdown menu/list with all the tabs or perhaps with the tabs that are not visible on the top right corner?
Is there a way to configure the table panel such that when I click on the > button on the right side to scroll the tab items, they scroll enough to make the next item visible instead of scrolling in small increments?
Ultimately, I could simulate the tab panel by adding a toolbar and buttons, and using the cardlayout. That would be my plan B.
Thank you
Update: I can set the flex: 1 property for each tab (inside tabConfig). I still have to figure out tooltips and enable the elipsis on the longer tabs that get chopped off.
There is a tabBar config for tabpanels, see here. Within this you can set layout properties, including overflowHandler, and one possible value is menu. This will do what you asked for in question 2. Add this config to tabpanel definition:
tabBar: {
layout: {
overflowHandler: 'menu'
}
}

Vertical scroll-bar of extjs4-multiselect is not displaying?

I'm using extjs 4.0.7 library. I have created UI as follows.
Landing page is a panel with border-layout.its north region have a panel with id: 'filterPanel'. This panel have a 'multiselect' component. Center region of landing page a tab panel, each panel having a grid.
Landing page has a listener, afterrender, on this listener I made filterPanel as collapsed by using Ext.getCmp('filterPanel').collapse().
The issue is, system not showing vertical scroll-bar when I expand 'filterPanel'.
If I remove panel collapse code from listener, scroll-bar is displaying.
Our requirement is filterPanel should be collapsed while rendering the UI, that's why I tried to collapse filter panel on landing-page afterrender listener.
Is this approach correct?
Regards,
Ajil
I got a work around for this issue. The steps which i followed is given below,
Add an expand listener for the panel here its 'filterPanel'
Remove all element from multiselect component store.
Reload multiselect store.
I'm sure its not a good fix , but time being its work for me.
Thank you all.

How to insert scroll bar in WPF in code behind for RadMenu

This Radmenu is dynamically created in code behind.Please let me know how to add scroll bar in this menu to limit the items in the submenu.
Check out this post from telerik forums.
Though it's in silverlight, I'm pretty sure you can use it as is.
Try explicitly setting the Height property of the Menu for that has a lot of menu items and that should add (Up/Down) button I believe
While not a scrollbar, you can set the DropDownHeight property of the RadMenuItem. It limits the height taken by the child menu items, and has up/down arrows to enable the scrolling.

In ExtJS, how can I create a panel and have it hover above a TabPanel?

I have a viewport with a tab panel in it. I'm trying to create a standard panel dynamically and make it visible. I'm able to create the panel and isVisible() returns true after calling doLayout on the viewport but the panel is not visible on the screen. Is there any way to make it visible (i.e., to hover above the tab panel)?
If you create the panel as a child of the document body and position it absolutely it should show above your existing layout. You could also (more easily) use an Ext.Window to do this.
