Positioning a component in Vaadin Designer 3? - vaadin

I use Vaadin Designer for framework 7. In this designer I can drag and drop a component and moving the component by clicking on it a moving it to the area I want.
And trying to do the same with the new Vaadin Designer 3. But it seems that AbsoluteLayout is deprecated and the replacement is Div. I drag a Div and on top of it a Button. But I can not move the Button by selecting it a moving it using mouse. Is this possible in Vaadin Designer 3?
BTW I dont want to position the Button using CSS.

Currently there is no AbsoluteLayout in Vaadin 10 and AFAIK not even a plan for such. As that isn't there and Vaadin Designer not supporting absolute positioning directly, this just isn't possible currently with Vaadin 10+ versions. Thus, if you need this feature, I suggest to go with Vaadin 8, which has many of most essential the improvements and will still be supported for many years.

Delphi 11.2 Speedbuttons don't show border at design time

Running windows 10 21H2. Just upgraded to Delphi 11.2 (from 11.1).
Speedbuttons (with Flat=False) do not show the button rectangle at design time. It does appear at runtime.
Most/all of our VCL projects have an empty style name. I have noticed that if I set the Stylename for the button (or even the form), then it shows normally. But is this the best way of handling it? Is there a global setting somewhere that can restore "normal" behaviour?
In 11.2 the Form Designer Options have a new option Mimic the system style, which is active by default. Disabling that should solve your problem.

How to fit Sencha GXT table in to the Div it contains

Hi I am new to Sencha GXT. I would like to know, How can I style a GXT grid.
I want to know this because I am currently integrating the sencha GXT grid into a Vaadin widget. I have successfully done that but, the problem is with the styling. Is there any documentation we can prefer.
Major problem is the grid works perfectly when I manually give it a width and a height but, What want is a to fit in to DIV it is in and re size the grid when the browser resizes.
Thank you.

Here's a link to the docs, basically it follow the GWT paradigm, if you've seen it before.
But since you want to integrate GXT Grid in a Vaadin widget I'd like to ask about your needings.
I know the standard Vaadin seems a little.."poor"..but I encourage you to check out the new Grid widget in Vaadin 7.4-beta (est release Feb.): it rocks!

Can I enlarge the menu font size in Delphi 2?

Everything I've found says I can't do this with Delphi 2's TMainMenu but if somebody here has managed it somehow, I'd really like to know the trick. I found code that changes the System menu font size but none that confines the change to only the application. Anyone here know how to do this or do I have to just accept Delphi 2's tiny menu font size that appears on today's large screen monitors? (Moving the app to an upgraded Delphi is not the answer I need ;-)
The only way to achieve per application custom menu fonts is with an owner drawn menu. Delphi 2 does not support owner drawn menu items directly in the VCL properties of a TMainMenu component. This support was introduced only in Delphi 4.
You could still implement an owner drawn menu, but it would involve implementing them using standard Windows API techniques, and handling the required messages on the forms which own the menus involved. It is not especially difficult but not as straightforward as the event based implementation available in Delphi 4 and later.
You can still use a TMainMenu to define your menus but in your application you would then need to programmatically set the owner draw flag on the menu items and handle the resulting messages appropriately. Doing this, you will need to handle all aspects of drawing the menu - you cannot simply set/change the font and leave the system to draw the menu items. You may also need to provide additional handling for any keyboard shortcuts you have set up.
If this is a viable approach then information on implementing owner drawn menus at the API level can be found here.

Delphi XE5 Android TButton colors

I need change color of 50 buttons in one form.
Every button another color and color want to set by code(no design editor).
It is firemonkey mobile application.
By my opinion, without making your own button that doesn't use FMX styles completely (which would break multiplatform compatibility if you are looking forward to support multiple platforms with their native styles), you may apply some filter on top of each of those buttons but on some styles this may cause the text not to be visible, implementing your own filter might get you the desired result:
Effect:=TFillRGBEffect.Create(Self);
Effect.Color:=$80FF0000;
Effect.Parent:=SomeButton;
Another way would be to take advantage of TColorButton with TText on top of it, but this way the entire button won't be filled with your color, but you can modify default/custom style for each platform in order to get what you need (this indeed needs to be done in the designer but you would have to create just one style for each platform you need to support and not 50 for each button):
Button:=TColorButton.Create(Self);
Button.Color:=$80FF0000;
Text:=TText.Create(Button);
Text.Parent:=Button;
Text.Align:=TAlignLayout.alClient;
Text.Text:='Hello';
Text.HitTest:=false;
Button.ClipChildren:=true;
Button.Parent:=Self;

Where can I find a movable toolbar demo?

At the top of the Delphi IDE is a toolbar with buttons grouped together on little movable trays. I'm trying to implement something like that, but not having much success. I've found TToolbar, but I can't figure out how to set up the movable trays. Does anyone know where I could find a simple demo app that shows how it's done?
I believe the webbrows.dpr located in the cool stuff demo directory (and included in all installs of Delphi since around Delphi 6 or so) contains just the demo you are looking for. This gives you the effect your looking for using only CodeGear supplied components. You add multiple bands and set the fixed size to false for the bands you want to allow to be movable.
You can try the Toolbar2000 Component from Jordan Russell or the TBX package wich is an extension for Toolbar2000 components.
Toolbar2000 is a set of components for CodeGear Delphi and C++Builder designed to mimic the Office 2000 look and behavior. It includes draggable and dockable toolbars and menus.

Bye.
You can put your toolbars in a standard VCL TCoolBar or TControlBar. AFAIR this can get a bit messy sometimes. For an example, have a look at the CoolStuff demo, as skamradt suggested.
