Size dinamically a Custom Control

Hi all,
in a dynpro I have two section:
- one with some parameters
- one with alv (using cl_gui_alv_grid).
I build the first section with a sub area and with a button to collapse and expand the sub area. All works fine.
The problem is that when I collapse the subarea I want to expand the custom control where the alv is.
I want to do something like the trx ME23N.
Any one can help me?
Bye
enzo

Any help would be appreciated !

Update of custom control

Hello experts,
I built a program with just 1 screen. This screen consists of 2 sections. Section 1 contains input fields for a selection, section 2 constains a custom control on which the selected data is displayed as pdf. For the creation of the pdf I use smartforms.
First selection works fine.
If I do a second selection with other selection values the pdf is not updated but displays the values of the first selection. How can I display the new values?

I don't know for sure, but your problem may be the font changes between Windows XP and Windows 7. By default, buttons have boolean text centered in the middle of the button. Even if the there is no text, the button will still resize with font sizes. To prevent this from happening, right click the button to select the properties and deselect the option to center the text. If you have disabled showing text, you will need to enable it, deselect centering, then disable text again.

Hey, at least I have a question to ask, instead of answering them... :-)
Actually, I already asked it in another thread, in one of my answers: [onMouseClicked Event Is Failing To Fire|http://forums.sun.com/thread.jspa?threadID=5391008] but I fear it is lost in a rather lengthly message, so I ask it in its own thread, because I was to bring the attention of knowledgeable people (hello Sun people! :-D).
The question is simple: In a custom control in JavaFX 1.2, with skin and behavior, how a control is advised when it gains or looses focus?
The purpose is to let the skin to change the look of the component upon these events, like it is done for standard controls (eg. putting a border around the focused control).
If the control is clicked, you know (unless it is disabled) that it will have the focus. But I see no way to see the lost of focus, nor when we gain (or loose) it with Tab/Shift+Tab (if it has focusTraversable to true).
I looked for onFocus() and onBlur() events (or similar), but found nothing. No mixin, nothing related in javafx.scene.input.TextInput and friends, etc.
I explored the Web but since 1.2 is still new, I found not much information. Only a fragment of source code in [Re: Further location optimizations|http://markmail.org/message/gsevtlkeq45rrdun] where I see scene.getFocusOwner() but this one isn't easily usable because it is package protected (and it is not an event, anyway).
A possible solution would be to have a timer to inspect the state focused of the nodes, but it is so kludgy I didn't even tried to implement it!
I hope I just missed the information... If there is no easy/official/working way in 1.2, I hope this will be corrected for next version!

That's a very good remark, handling of focus highlight shouldn't be done at control (model)'s level. I hesitated to put it in behavior, but it feels more natural in the skin, so I did as you suggested.
you'll need an interface, and JavaFX does not do thatYou have mixins. But I didn't used them here.
focused variable never is set to trueHave you included the
public override var focusTraversable = true;
line?
To support multiple skins, my control becomes:
public class StyledControl extends Control
// Data related to the control (the model)
public var count: Integer;
public override var focusTraversable = true;
init
    if (skin == null) // Not defined in instance
      // Define a default styler
      skin = ControlStyler {}
package function Incr(): Void
    if (count < 9)
      count++;
}quite bare bones (I intendedly keep the model simple).
Note I still define a default skin in case user doesn't provide it: they shouldn't care about this detail unless they want to change it.
I defined an abstract default skin, implementing most variables (particularly the public ones that can be styled) and the focus change:
public abstract class DefaultControlStyler extends Skin
//-- Skinable properties
public var size: Number = 20;
public var fill: Color = Color.GRAY;
public var textFill: Color = Color.BLACK;
public var focusFill: Color = Color.BLUE;
package var mainPart: Node; // Decorations (id, focus) are kept out of layout
package var focusHighlight: Node;
package var idDisplay: Text;
package var valueDisplay: Text;
init
    behavior = ControlBehavior { info: bind control.id }
    node = Group
      //-- Behavior: call controller for actions
      onMouseReleased: function (evt: MouseEvent): Void
        (behavior as ControlBehavior).HandleClick(evt);
postinit
    // Once defined by the sub-class, insert into the node
    insert [ mainPart, idDisplay, valueDisplay ] into (node as Group).content;
public abstract function ShowIncrement(): Void;
var hasFocus = bind control.focused on replace
    if (hasFocus)
      ShowFocus();
    else
      HideFocus();
// Default handling of focus display, can be overriden if needed
public function ShowFocus(): Void
    insert focusHighlight into (node as Group).content;
public function HideFocus(): Void
    delete focusHighlight from (node as Group).content;
public override function contains(localX: Number, localY: Number): Boolean
    return mainPart.contains(localX, localY);
public override function intersects(localX: Number, localY: Number,
      localWidth: Number, localHeight: Number): Boolean
    return mainPart.intersects(localX, localY, localWidth, localHeight);
}and the concrete skins implement the mainPart, idDisplay, valueDisplay, focusHighlight nodes, override ShowIncrement with an animation, override getPrefWidth and getPrefHeight to set to mainPart size and might override ShowFocus or HideFocus (if we want it behind mainPart for example).
The behavior is:
public class ControlBehavior extends Behavior
public var info: String; // Only for debug information...
// Convenience vars, to avoid casting each time
var control = bind skin.control as StyledControl;
var csSkin = bind skin as DefaultControlStyler;
public override function callActionForEvent(evt: KeyEvent)
    println("{info}{control.count}: KeyEvent: {evt}");
    if (evt.char == '+')
      Incr();
package function HandleClick(evt: MouseEvent): Void
    control.requestFocus();
    Incr();
function Incr(): Void
    control.Incr();
    println("{info}: Ouch! -> {control.count}");
    csSkin.ShowIncrement();
}and knows only the abstract default skin (to apply feedback of user input to skin).
I use it as follow:
Stage
title: "Test Styling Controls"
scene: Scene
    width: 500
    height: 500
    content:
      HBox
        translateX: 50
        translateY: 100
        spacing: 50
        content:
          StyledControl { id: "Bar" },
          StyledControl { /* No id */ layoutInfo: LayoutInfo { vpos: VPos.BOTTOM } },
          StyledControl { id: "Foo" },
          StyledControl { id: "Gah" },
          StyledControl { id: "Bu", skin: AltCtrlStyler {} },
    stylesheets: "{__DIR__}../controlStyle.css"
}BTW, I tried layoutY: 50 in place of the layoutInfo definition, but the control remained at default place. Am I reading incorrectly the ref. or is this a bug?

Flexible custom control

Hi all, I am developing ALV using OO concept in which custom container is placed on custom control, i have kept that custom control of full screen size but my requirement is to make custom control flexible dynamically while we are adjusting the size of main window.
I used Resizing option while designing the layout, but still its not properly serving my purpose. Is there any other way to work with it?

There is no direct option which will resize custom control/container when resizing window. The one you already set will prevent from making it too small. You may however, set custom control large enought (i.e fullscreen) but resize container inside it by using methods SET_HEIGHT and SET_WIDTH of cl_gui_custom_container .

Is it worth it to make custom icons for a custom control/indicator?

I was making custom icons (well not very custom, but still at least somet ext) for controls and indicators, when I realized that the only times you see them are when you open the control, itself, ot if you hover over it in the project with context help on.
So the question is:
Is it worth it to create a custom icon for each custom control you make, if it will be seen only rarely? (The exception being a cluster, since, in the later versions of LabVIEW, you can actually represent your cluster on the BD as the icon you made for it, so it definitely IS worth it to make an icon for it.)
Thanks!

I'd like to add another time that you see the control's icon, is when it is a type def cluster, and you have it as a constant on the block diagram. Then double click the border to shrink the cluster. It will shrink to the size of the control's icon.
I also hardly ever make a control icon. Only when it is on the palette in a reuse package.
Yeah,t hat's what I meant in my original post, although you CAN represent a cluster constant on the BD as an icon - but it's just the little thing on the bottom of the typdef'd cluster because it obviously has no actual icon.

Creating Custom Control on screen dynamically

Hi All,
Is it possible to create custom controls dynamically through ABAP code.
If not, can we change the size of custom control at run time through ABAP code.
Thanks

Custom control switch

Hi, I'm a relatively experienced Labview user, but i have never created my own custom controls.
I need to make a 2 pole switch control for a front panel to indicate signal paths.
I have done some reading on the ni website about creating or modifying controls, but actually getting the controls editor to give me what i want is driving me crazy.
What i need is something like this:
(Would be nice to have a mirror version too)
I have been trying to modify the standard boolean toggle switch, but i do not really understand how edit the image parts works. i,e how are the different states handled? an image for each - if so i cant see how that works.
also i may have an editor problem, beacuse what ever i do when i copy to clipboard - edit - paste, i get an image with non-transparent background. (i have used both gimp & paint.net)
If anyone is a whiz at this and could help me out i would be most grateful.

OK here is the low down on the custom control.
First creat a custom control in LabVIEW and add an OK button. Next you need to click on the wrench symbol on the menu bar to edit the button images.
Next you need to right click on the button and choose the option to import File at same size: Browse and fine the image that you want to import fo rthe up (false) condition.
Next if you right click the button and select the "Picture Item" you will see all of the pictures that you need to replace. They go in the order up, down up click and down click.
Select the next image and redo step two until all pictures for the button are replaced. Should go false state true state false state true state.
To test the control click on the tweesers icon and push the button.
Save the control and enjoy.
I hope this help

LabVIEW and custom controls

Hi all,
I'm an italian PhD student working with Polytechnic of Bari.
I'd like to submit to this forum a question about LabVIEW and custom controls in form of ActiveX components.
Some introductory word about my problem will be helpful: in the past few months here at Polytechnic of Bari my colleagues and I developed some useful ActiveX controls with custom functionalities to use in LabVIEW.
For example we developed a "contraves", an
"endless knob" and a useful counter with a scale very similar to that of standard gazometers or energy counters.
However we are experimenting some difficulties with the integration of these controls in LabVIEW; the controls are correctly imported in our VIs with using the ActiveX Container but...
in the block diagram they appear as ActiveX references and we must use property nodes to access even their most useful property (value).
Please, do someone of you know if (and eventually how) is it possible to integrate more deeply the controls in the LabVIEW environment?
Do someone of you know if it exist an hypothetical "Custom Controls SDK" for LabVIEW more advanced of that integrated in LabVIEW 6.0?
Any hint would be appreciated.

The first step is to build a VI that contains the panel and diagram
elements that you want to drop all at once. In your case, drop the
ActiveX control at a good size, and on the diagram, you can wire it to
helper VIs, property nodes, etc. The VI's icon and name are important
as that is what will show up in the palette menu representing your
control. The connector pane isn't used.
With the VI constructed, you want to add it to the palette menu. In the
Tools menu, Advanced, there is an item about half way down for
Customizing the Palette menu. You will need to build a New Palette Set
using the ring and name it whatever you like. You can now add your VI
wherever you like. Most likely you will want to right click to add a
new subMenu in the Controls palette and place it in a new .mnu file. In
the subMenu, right click to add Control. The file dialog will open
allowing you to select a control file to add to the palette. By
changing the filter from .ctl to all, you can insert VIs into the
controls palette.
All VIs inserted into the Control palette will act as merge VIs, meaning
that when dragged to a panel, the panel elements will be merged into the
destination panel, and the diagram elements will be merged into the
destination diagram.
For others that want to have these on the Functions palette rather than
the Controls, you add the VI to the Functions palette, then popup on the
palette item and check the menu item to make it a Merge VI.
When it comes time to distribute, you will want to give out your .mnu
file and the VI of course. Easiest is to place both of them in
user.lib. If you want the items to go at the top level of the palettes,
then you can add them to add-ons inside of vi.lib, but this causes more
upgrade challenges.
Hope that helps.

Slider custom control

Hello,
Does anyone know how to increase the size of the digital display increment arrows on a slider control? I want to make the arrows bigger but the "custom control" selection under edit is grayed out. I am working with a 30" monitor and would like them to be twice the size.
Thanks,
John

Hi there John,
the procedure seems to be a bit tricky, but you can customize the increment arrows by first switching to the customize mode, then selecting the digital display and only after that it lets you select the Customize control -option. Try it. This works at least in LabVIEW 2009 and 2011.
Cheers,

Auto resize (dynpro / custom control / html_viewer)

Hello!
I'm using a dynpro + custom control + html_viewer.
Is there a way to make the html_viewer size dynamic? So that if resize the SAP Window the size of the html_viewer changes to the avaliable space on the screen. I don't want fullscree because i want to see the SAP standard menu.

I need create a custom control for visualization HTML

Hi guys,
I need create a custom control for HTML files visualization on SAPGUI JAVA. I created a sample program and perfectly run on SAPGUI Windows.
Thanks.

Hi,
Just as a quick start
http://gumbo.flashhub.net/sizer/ (view source enabled).
this uses a skin to make a titlewindow resizable, its not about the skin as much as giving you a starting point for resizing code.
if you look into the skin you will see these functions
protected function sizer_mouseDownHandler(event:MouseEvent):void
OldX=event.stageX;
OldY=event.stageY;
systemManager.addEventListener(MouseEvent.MOUSE_MOVE,startResize);
systemManager.addEventListener(MouseEvent.MOUSE_UP,endResize);
protected function endResize(event:MouseEvent):void
systemManager.removeEventListener(MouseEvent.MOUSE_MOVE,startResize);
systemManager.removeEventListener(MouseEvent.MOUSE_UP,endResize);
private function startResize(event:MouseEvent): void
hostComponent.width -= OldX-event.stageX;
hostComponent.height -= OldY-event.stageY;
OldX=event.stageX;
OldY=event.stageY;
The idea is to have a hit area on your custom component (a corner, or all corners). You capture the mouseposition when you mousedown then in the mouse move eventlistener you update the object size with the difference between current X and Y from initial X and Y.
Hope this gets you started.

Custom Control Help: Draw a line and output start and end points

I'm looking to find or make a custom control (or simple subVI) that will appear as a 100x100 unit grid and allow me to draw a line from one point to another on that grid. It will then output the (x,y) of the starting and end point of that line on the grid. Any help or ideas?
Thanks,

Solved!
Go to Solution.

What you basically want is a loop with an event structure where you process Mouse Down, Move and Up events for your controls. There are any number of ways of implementing something like this, but this one will probably be the simplest:
Use a multicolumn listbox or a table for your grid. Hide the scrollbars and headers.
You can use the ActiveCell property with -2,-2 to select all cells. You can then use the cell size property to set the exact size of the cell.
Next, you put a picture control on top of the table and color its background transparent so that the table shows through. You use property node to make sure the two are aligned to exactly the same spot and size.
You use the mouse events on the picture control to detect the clicks and moves.
You use the table's Point to Row Column method to translate the event's position data to a cell.
You use the picture control VIs to draw the line on the picture based on that data.
You can even color the selected cells in the table using the table properties.
If you want to simplify things somewhat, you can also use the timeout event instead of the Mouse Move event to draw the line, but then you'll need to keep the timeout value in a shift register and reset it to -1 (no timeout) when the Mouse Up event happens.
I would also suggest processing Mouse Enter and Leave events to change the cursor and cancel if the user leaves in the middle of dragging.
Try to take over the world!

Making Custom Controls

What tool do I use to make Custom Controls and vi's from scratch

The sticky point is "from scratch". This is not fully possible!
Using the control editor, you always start with an existing control, which you then modify by changing cosmetic properties such as size, arrangement, color, decals, etc. You cannot start from scratch, but you can typically come close to your ideas by starting with an existing control that has all the features you want.
More here: Creating Custom Controls, Indicators, and Type Definitions
For even more complex tasks, you can make an XControl. This is basically a control that can consist of as many controls and indicators as you like, can have any datatype, and contains complex code and logic.
More here: Using XControls (There is even a tutorial)
Good luck!
