buttons that shown in design tab aren't visible in emulator - android-studio

I want to make simple login form. I've tried to add "NEXT" and "REGISTER" buttons. I can see them in the design tab, but can't in emulator. Moreover, i tried to add some extra buttons to see it works. It looks like that: screenshot

How to programmatically remove popup widget (added by editor.addWidget) and how to detect when it was removed by editor

I'm trying to use popup widget to show suggestions like described here https://github.com/nhn/tui.editor/blob/master/docs/en/widget.md
Widget is working fine. But I don't have any reference to created widget.
So how can I remove it programmatically (for example when user press Escape)?
And how can I get some event when popup was removed by editor (for example if user clicked outside the widget)?
For 2 i'm using MutationObserver for now but this looks weird. For 1 I don't have a solution at all and can't find anything in docs.

Download functionality in Tabulator

i would like to use the functionality to allow table data to be downloaded by a simple button click as described on
http://tabulator.info/docs/4.2/download
I hoped i could get a working example on "view source", but its only code snippets needed to configure it.
Could someone give me a complete example how to use it?
I got so far, that i have the table running and the buttons are also present, i am just missing the buttons actually doing something on clicking them.
Thanks in advance and have a nice day
Ingo
The complete example is right there on the page you linked. Click the green "View Source" button located under the table, which will expand some snippets. Under the "JavaScript" snippets there are button click handlers commented with //trigger download of data.*** file. That code uses jQuery to specify what the button calls when it is clicked. The buttons call table.download() with parameters to specify the format and download filename.
You can also see it here: http://tabulator.info/examples/4.2?#download

Expanding button to autosuggestbox in UWP

I am trying to configure a button within my UWP app to expand in to an AutoSuggestBox on click. This behavior is mentioned in this post:
https://msdn.microsoft.com/en-us/windows/uwp/controls-and-patterns/search#Implementation
I tried utilizing a flyout on the button click, but it doesn't give me the desired effect. Is there an existing control that can do this or will I need to roll my own XAML of an existing control?
The behavior you see in the blogpost can be easily achieved by having an autosuggestbox hidden behind the button, then after on button click fading out the button and resizing the autosuggestbox to the desired width.
There's no way to "expand" a control into a different one, but you can make it look like that happens :)

SharePoint default modal dialog box not showing buttons

I've been doing searches trying to find help on this, but so far all I have found is how to set options for popping up a SharePoint modal dialog box from custom code.
However, I haven't created any custom web parts to display modal dialogs. What's happening, is if someone clicks the upload document button in a library, the upload document modal dialog comes up, but the ok and cancel buttons are half off of the bottom of the box. Users can click on them, but it just doesn't look very good.
I started playing with the CSS to make the modal dialog box bigger to reveal the buttons, and that works for the most part, but the real problem is the grant user permission dialog box.
When that is clicked, it doesn't show the ok and cancel buttons, and maximizing the dialog box doesn't reveal them. The user has to hit tab about 5-10 times before the focus moves to the ok button and is then clickable.
I would post an image, but I don't have enough reputation to do so.
Has anyone come across this? It seems very strange that the out of the box setting would have this problem.
The CSS that I use to adjust the height and width of the modal dialog is:
.ms-dlgFrame, .ms-dlgContent, .ms-dlgBorder, .ms-dlgFrameContainer
I'm just trying to set the height/min-height values, but I haven't had much luck.
We're using Internet Explorer 11 to view the pages.
Stevangelista actually pointed me in the right direction, I wish I could mark comments as answers, and since I'm new I can't upvote the comment, but here's the solution:
I am using a customized master page, and that comment had me take a look at the elements in the page.
Since the master page is being used in the dialog boxes as well, I used the s4-notdlg class to remove parts that weren't needed in the dialogs. Those parts were pushing the buttons below the bottom of the screen.
I'm not a css expert, so there may be ways of keeping those parts and still have the buttons accessible, but the particular issue I was trying to fix was resolved by using the s4-notdlg class to objects in my custom master page.

left and right command menus in LWUIT form

Using LWUIT framework to develop mobile application.
In LWUIT by default first command is placed in the left and subsequent commands will be placed in the right menu of the form including the command which is already placed in form left.I need to add two menus to form.Left menu contains general application specific commands such as "Minimize","Back" and "Exit". Right Menu contains screen specific commands such as "Play Audio","Play Video" etc... Initially left softbutton of the form contains the text "Options" and the right softbutton of the form contains the text "Menu". When user selects "Options", a menu will be displayed with the following commands:
Minimize
Back
Exit
When user selects right soft button "Menu", a menu will be displayed with screen specific commands:
Play Audio
Play Video etc...
Commands of the right menu keeps changing from one form to another form, whereas the commands of left menu remains the same for all screens(forms). I know command menu can be customized by overriding "Form.createCommandList(Vector)" which returns a list. But here in my case I need two lists(menus). One at the left of the form and the other one at the right of the form.Please do help me in resolving this issue.
A LWUIT menu is just a dialog containing a List (or buttons for touch menu or pretty much anything you want), so to implement this just create a Command called options and place it in the left soft button. When options is pressed just show the dialog with your "additional commands". Since a List can accept a command array or vector doing something like this can be really easy.
You can look at the code for MenuBar which is pretty simple, you can also replace the menu bar component in the latest version LWUIT (SVN at the moment) but that seems redundant for this particular use case.
