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!

Making custom controls blink

Hi,
I've been trying to build some custom boolean controls and indicators, which works fine, except most of their properties are now useless. In particular, i can't make them blink anymore.
I understand an imported bitmap wouldn't be able to blink, so here's my question : is there a way, or a tool, that will allow me to make custom controls as useful as regular controls ?
Any clue or insight appreciated.
Silent.

I have never found a program that allows the user to create LabVIEW pretty controls. I do have a couple of workarounds though.
You could put the custom controls on top of square classic control and color the classic contol to be the background color. Then you can make the classic control blink to draw attention to your control.
You can also use a classic picture ring that is colored transparent and programatically toggle to the binking image.
Variation on the theme:
You can import a PNG image with transparent colors and place it on top of another control which blinks allowing for the transpartent part of the image to become colored.

How to use custom control in Dialog Programming?

How can I call a subscreen using custom control in Dialog Programming?
The required subscreen contains a calender. Any class or something available for this purpose. Please suggest.

TOP of PAGE using ABAP oo with single CUSTOM CONTROL

Can anybody please tell me how to handle TOP_OF_PAGE using ABAP OBJECTS with a SINGLE CUSTOM CONTROL and not with SPLIT CONTAINER(i.e. using single CL_GUI_CUSTOM_CONTAINER and single grid CL_GUI_ALV_GRID ). Is it possible if so Please help me out?

Hi Ravi,
Here is my code. i didn't handle the top_of_page event yet but created a method to handle.

Custom control color property

With the included controls like the OK boolean you can change the true or false color by going to Properties >> Apperance >>Colors. Then click the color box to change the state color. Is it possible to do the same with a custom boolean control?
I have searched some and it does not sound like it is possible, but I figured that I would ask. I have a diagram where I used some pipes from the DSC module image navigator to make some boolean pipes. I just changed the properties for the different colors then pasted them into a boolean control for true/false cases. But now I am thinking of changing the colors from gray/red to gray/green. Is there an easier way than just starting over and making new booleans with the desired colors? Or is there a better trick for custom controls I don't know?
Thanks
Solved!
Go to Solution.

Here is a sample of the control as a type def and a vi with the Colors(4) property cluster. I must be doing this wrong or not explaining it correctly. So if you could look at the files and be able straighten me out I would appreciate it.

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.

Veristand Custom Controls

I am just starting to use the Veristand evaluation copy to see if it can do what I need it to do. It seems very customizable, and I was trying to create custom workspace controls through Labview. I would like to get things like radio buttons, lists and drop down menus into the workspace to control my model. I tried simply taking one of the numeric controls and replacing it with one of the previously mentioned controls, but it gave me an error saying that they were unsupported. It seems like I would be able to do this using the Free Label Template, but I'm not quite sure how to do that. I was able to find a custom indicator example (the min/max one), but was unable to find anything involving custom controls. Are there any examples or tutorials I could look at? How would I go about making some of those Labview controls into things I could use in the Veristand Workspace?

Hi erric, I have some answers for your issue.
1. I attached a zip file that contains your control renamed and build a project in it. You should be able to unzip it, check the build specificiation and make sure the output destination is the C:\Documents and Settings\All Users\Documents\National Instruments\VeriStand\Display Templates. Trigger a build on this and you should get EricHettlerSample - Radio.vi and EricHettlerSampleControlSupport.llb in there. Once you have this run a workspace you will be able to drop the EricHettlerSample - Radio control from the control list.
2. For the explanation. I think when you do a save as on the min-max example you download from the web LabVIEW cross link the vis that is in the llb with the one in the vi.lib. So doing a save as will not work. What will work is that you create a project and setup a source distribution to build the custom control. These are the steps I take based on your attached file:
Rename in windows explorer the attached numeric indicator - radio.vi to EricHettlerSample - radio.vi
Open LabVIEW convert the .llb you attached to a directory.
Create a new project file.
Open EricHettlerSample - radio.vi under my computer, when LabVIEW prompts me for some VI i look for them in the converted llb directory. Note that LabVIEW will find most of the files under vi.lib since these are the files that NI VeriStand install to labview directory.
Once I added the some of the vis, I mass compile the project.
Create a source distribution. Add the EricHettlerSample - radio.vi. Go to source file setting make the main vi go to the template folder and everything else go to a llb folder.
Trigger the build, LabVIEW will do a better job creating an isolated component that is correctly linked.
As a rule you always want to create a project to build a custom control, since Save As will not always worked with the LabVIEW VI linkage in NI VeriStand.
To create a completely base custom control project what you do is:
Copy C:\Documents and Settings\All Users\Documents\National Instruments\VeriStand\Display Templates\Decoration - Free Label.vi in windows explorer to a directory of your choice.
Do a rename on the VI in window explorer.
Open LabVIEW create new project add the renamed VI under my computer. This will create a blank project for customizing custom controls.
I hope this helps, let me know if it still does not work for you.
Also if you still bothered by the error messages that shows up you might want to clean up C:\Documents and Settings\All Users\Documents\National Instruments\VeriStand\Screens directory since this directory is where NI VeriStand caches all the controls you drop in the workspace. So if you have a control that cannot be loaded delete all vis in this directory should remove the bad vis.

Custom Controls

I've followed the description on how to create custom controls from the National Website..I think it was the Knowledgebase.
I have 18 indicators that are on my front panel. I modified one using custom controls. How do I replace the other 17 with the custom control I created for the other one?
Solved!
Go to Solution.

Making sure I did this right...pressed for time.
I create the custom control. Which I've already done. I save it as a "type def" from the drop down menu in the upper left of the edited control next to the wrench icon.
I then can do a "replace" of that indicator ??
That looked like it worked..thanks!

Issue in Custom Control UI element

Hi there,
               I have created 2 custom controls(SAP mobile 7.1), one for rendering images(actually map images) and another for capturing user's signature. Both are integrated into the main application and works fine when alone. But when present together, certainly on different screens in the main app, still it works but with rendering problems. Say when navigating from the screen that displays the map custom control to the screen that has the signature capuring custom control, the map image is still getting displayed over the signature custom control view.
           I wonder , if the problem is with disposing of the custom control. Can anyone suggest how to do that. Or something else has to be done?
Regards,
Aravind

Hopefully someone more knowledgeable about custom controls \ SWT can add some input
I do know disposing the SWT controls is important but not sure if it would solve your problem
from our application that uses a few simple custom controls together, we definitely needed to use dispose or it would cause memory consumption issues and slow performance
within the constructor
[Text object].addDisposeListener(this);
method to dispose color and fonts used
public void widgetDisposed(DisposeEvent event)
              font.dispose();
              amber.dispose();

Team Foundation Server 2013 Refresh button not refreshing Custom Control values in TFS Templates

Hi all,
We have recently migrated from Team Foundation Server 2010 to Team Foundation Server 2013 Update 2. In TFS 2013 template design we found the refresh form control (inbuilt control of TFS) which is unable to refresh the custom control values that is built
by us. Is there any way that we can programatically modify to enable the refresh button work with custom control.
Please find below screenshot link for reference.

Hi SaranRam,
The refresh button is there to allow the data that populated the work item to be refreshed. The data that you want refreshed is part of the rendering of the form and would only be refreshed when the browser refreshes. Refer to MrHinsh's reply in this
page.

OOP ALV report custom control performance problem

HI
how to write OOP ALV report without custom control.. Actually with custom control which taking long time... and time out happens for huge selection of data..
Regards
Roops.

timeout is not an alv problem. If you try to display a "huge" amount of data, any display technology will fail. Even sap programs fail, their wise solution is to ask user to restrict data to be displayed. Or reduce database selection time, or display amount. Or propose the user to download data as a spool, or output to a file on server.
Otherwise, read some advices about how to handle timeout in [Note 25528 - Parameter rdisp/max_wprun_time|http://service.sap.com/sap/support/notes/25528].
About your question, if you still want to try, look at [example code with alv class cl_salv_table for simple display|http://help.sap.com/saphelp_nw2004s/helpdata/en/f9/1ab54099de3726e10000000a1550b0/frameset.htm]

How to create a custom control of a button where the look will be applied to all others but not the Boolean text?

Hi all
I would like to create a customized button as a master so that if I change the look of the master all other buttons will change too.
I have done this with a custom control as a "strict type def" otherwise the look will not change BUT If I do this as a strict type def I cannot change the Boolean text anymore which should be different on every button.
How can I create a master control of a button where the look will be applied to all others but not the Boolean text?

I don't think you can do that. I just looked and as I suspected the Boolean text property is read only for strict typedefs so you cannot use property nodes to change the text.
As a workaround just make it a typedef. When you want to change the look open the typedef and make it strict, make your changes, then make it non strict again. You will have to update the Boolean text again for all instances. Kind of a pain. Maybe this is something for the idea exchange.
Kudos for being sneaky.

How do I find the EventID of an event in a custom control?

Hi all,
I have a custom control created in VB .NET that I have embedded into a SAP screen using a wrapper class as described in Thomas Jungs example: <a href="/people/thomas.jung3/blog/2004/09/01/using-net-windows-controls-in-the-abap-control-framework .Net Windows Controls in the ABAP Control Framework</a>
My problem is that I cannot get the wrapper class to react to any events raised by the custom control!
I do not know how to find what the EventID is of an event so that I can register it in the class - do you know how to find this EventID? Or even if this is the problem?

How to limit the number of rows in the Custom Control box

Hi All,
In my Module pool screen I have a Custom Control box for providing some free text as input. Now, there is no limit in the number of rows allowed for this box.
But, the requirement is, it should have the maximum number of rows = 99. and each row should have maximum length = 60 characters.
User should not be allowed to enter more than 60 characters per row and more than 99 rows.
Could you please let me know how to do this..? Are there any methods available which controls the maximum number of rows and maximum length per row..?
Please help me in resolving the issue. Thanks in advance.
Thanks & Regards,
Paddu.

By "Custom Control Box", do you mean a Custom Container or a Table Control?
Anyway, I suggest you to use a table control (not a custom container as your requirement seems to be very precise on that point, maybe ask your client twice to make sure). Look at the examples of table controls in ABAPDOCU transaction.
