Hallo Herr Köhler,

Ist das ein doppel Post?

Mit freundlichen Grüßen

Awesome. Great.

Hi Martin,

$cando() is an inbuilt method that proves if a certain method is available. In this specific case it checks if the $getID() of the container can be executed.

The container can be either the container form that contains the subform instance or it can be the form that opened the popup form.

So the $load will be called with an argument that is the id from the container.

I hope that makes sense.

Best,

Andreas

Hi Khanh,

Hi Khanh,

Again not really recommendable. However under certain circumstances it might be necessary and it is possible.

For example you can have the following code behind a button. When the button is clicked it will generate a copy of the button:

On evClick
    Do $cinst.$objs.$add('newButton',$cfield) Returns lNewButtonRef
        If lNewButtonRef
            Do lNewButtonRef.$top.$assign(30)
            Do lNewButtonRef.$left.$assign(250)
            Do lNewButtonRef.$text.$assign('I am new')
    End If

Note that $cfield is the reference to the field where this code is actually located. In this case it is the button you have clicked on. You can also refer to another object by using this notation:

$cinst.$objs.myOtherField

“lNewButtonRef” is a local variable of type item reference. This is a pointer to the new field and can be checked with the IF statement. It can also be used to assign other properties such as $top, $left, $text etc.

So in theory you could dynamically create your UI but then you will lose the advantage of having a graphical design tool etc. This is one of the strength of Omnis development.

So why not simply drag the desired object from the component store onto the form?

Andreas

Hi Khanh,

with this technique you can copy objects in a remote form.

However the question is if this is a good approach. Designing the remote form by adding objects dynamically will be slow and is not using the remote form class as it has been designed. The class is a kind of a database record that is holding its fields. The whole library is the database that holds the UI and the functions.

If you still need an example how to copy objects in a remote form let me know. I will send some code how to achieve this. I am just afraid that Omnis is then kind of misused by storing the field information somewhere else. I have seen this in other projects which makes things unnecessary complex.

Hi,

There are color schemes that you can use. Here is the documentation: https://www.omnis.net/developers/resources/onlinedocs/WebDev/03jscomps.html#js-themes

For fat client please see here: https://www.omnis.net/developers/resources/onlinedocs/Programming/01omnistools.html#color-themes-and-appearance

I hope this helps.

Best,

Andreas

Hello Khanh,

There is a typo in your code. You would need $designcols (with the “s”).

Hi Mischa,

I would recommend using a data grid instead. This one has $multipleselect and if switched on you can select multiple list lines.

The complex grid is designed for always being enterable, hence not really useful for making a user selection.

What you probably could do is adding a control that shows the status of a line. For example you could use a checkbox or an icon to show if a row has been selected. You could also change the text color of certain objects (see here: https://www.omnis.net/developers/resources/onlinedocs/WebDev/03jscomps.html#exceptions) or use a page pane that shows different pages by setting the paged panes $dataname to a column of the list. https://www.omnis.net/developers/resources/onlinedocs/WebDev/03jscomps.html#using-dataname

Best,

Andreas

Hi Nathanaël,

I would think this is due to asynchronous execution. Omnis starts the worker and continues to execute that method. Therefore you need to have a callback that can be used to get the result from Python.

Best,

Andreas

Hi Martin,

There is a $iconsets property of your library. This is also documented here: https://www.omnis.net/developers/resources/onlinedocs/WebDev/03jscomps.html#icon-sets

Best,

Andreas

[Andreas Pfeiffer]

Hi Martin,

I am not sure if I understand you well.

Do you mean where to copy the icon folder? It is described in the readme.txt file.

Does that help?

Best,

Andreas

Hi Nathanaël,

I think Götz already covered this.

Hi Martin,

What chapter in the training manual do you refer?

BTW. Do you mind not mixing the threads?

Thanks and best regards,

Andreas

[Andreas Pfeiffer]

No worries. Have a great day!

Best,

Andreas
