Function Parameters Properties Window

[hamidkassam]

Hi,

Does anyone know how to set the column size for the Parameter, Value and Default columns when vieiwng the function parameters in the Study Properties window?

When I bring up the Study Properties window on a formula I created, the scroll bar on the right is not always there. It comes in view temporarily if I manually make the Parameter column narrower by left clicking and dragging it to the left. The next time I open the window, the scroll bar has disappears. I would like to set the parameter column to a fixed size so that the scroll bar is always visible.

The alternative is to write my labels on two lines. Again, is there a way to do this?

Any help on this will be much appreciated.

The attached file is a snapshot of my Propertiees window.


Thank you.
Hamid.

Hello Hamid,

The column size in the Study Properties window is not customizable. It's width is determined by the data in the column.

Also, the label cannot be wrapped to a second line currently. Please feel free to suggest that feature to our development team at [email protected].

The vertical scroll bar issue was a problem in older versions. You may need to upgrade to the latest version. What build number are you currently using (Help-->About)?

Jason,

Thank you for your reply. I am currently on Version 8.0 (Build 779) 05/15/2006. Is there a later build that will at least resolve the scroll bar issue?

It does seem to me that the ability to control the shape, size and look of the Study Properties window would satisfy a lot of formula builders. I will pass this request to the development team as suggested.

On a similar topic, is it possible to build a Study Properties window similar to the ones in the built-in functions e.g. the RSI like the one below?

Thanks again for your help.
Hamid.

Hello Hamid,

There is a later build (782), which is still 8.0. You could try installing that build here. However, build 779 shouldn't have the bug. Can you post your formula that you used for that example image. Or at least the preMain() section. I'd like to test it on my end.

Modifying the gui, or creating the similar gui controls as the Basic Studies is not possible through EFS at this time.

Jason,

Here is a section of the preMain code as requested.

I wonder if the problem is due to using an array for each FP instead of using a simple var?

I will upgrade to the later build as mentiioned.

Thanks again,
Hamid.

Jason,

Well, I just installed the new build and the scroll bar is back without me having to do anything to the columns. If that works every time I open up the window, then maybe that 's all that is needed, but if you have any suggestions in the fp code, I would really appreciate your input.

Regards,
Hamid.

Hello Hamid,

Your preMain() code is perfectly fine. I had thought the scroll bar fix was included in the 779 build. Good to know all is well for you now with the new build. This shouldn't be a problem for you anymore.

Hi Jason,

I may have spoken too soon. It worked fine yesterday after I installed the new build, but I have the problem again today. i.e. I have to manually change the column width to see the scroll bar.

Any further thoughts on this?

I am happy to hear the fp code is fine.

Thanks,
Hamid.

Hello Hamid,

I've tested the preMain code you posted as well as several other formulas and I'm not able to reproduce this problem. I did notice that the preMain() code you posted is not the same as the formula parameters that appear in the first image you posted. Please post the exact preMain() code you were using when that image was created so I can try to reproduce the exact same scenario on my end. Any other specific actions you're performing on your end that consistently reproduces the problem would also be helpful.

Hi Jason,

Here is the full list of fp's I use. Sorry I did not provide this earlier because I did not want to overload you for the test - but perhaps it may be required at your end to recreate the problem.

I will attach the study properties window that got created with that code in the next post as I am not sure how to attach multiple files.

Thanks.
Hamid.

Jason,

Here is that window mentioned in my previous post.

Hello Hamid,

Thank you for posting your complete preMain code. I see what the problem is now, which is slightly different than the previous scroll bar bug I was thinking of.

The problem is caused by the combination of the character length of some of your parameter options and the character length of your labels. The options associated with the "Strategy Help" parameter are the main issue. The solution for now is to use shorter descriptions for your labels as well as shorter strings for your parameter options.

I also tested your preMain code against an internal beta version for 8.1 and the problem does not occur. In 8.1 you will be able to go back to longer labels and descriptions if you like. For now, you'll need to implement the suggestion above.

Hi Jason,

That's great. Thank you very much for pinpointing the problem. I think I am going to implement as you suggest until release of 8.1

That brings me to another item on the wish list - the ability to insert a help file that a user can open and read instructions and explanations for each of the parameters and strategies. Maybe I should send this to the development team too.

Thanks again,
Hamid.

Hello Hamid,

You're most welcome.

As for ideas and suggestions for development, please feel free to submit as many as you like.

For your help file idea, you could alternatively draw an image or button on the chart and assign a url to it. When clicked, it will launch the url in a browser . This would be a better route to take in my opinion because any updates to your documentation will only need to be published to your website and not have to be stored locally by each user. To add a url to a drawTextRelative() object add the following to the text parameter, "@URL=http://www.yoursite.com."

Jason,

Thank you for the suggestion on the help file. I will keep that in mind when I have some solid studies completed. I have a domain name but don't have a website yet - that will be forthcoming soon.

I really appreciate your prompt responses to my questions.

Regards,
Hamid.
