But then I get this error below

Show the code...

@Radio1985
...As @jsulm says, and show the values of the "fromRow" and "toRow" you are passing....

I am using the same code above. Added the additional lines below:

int row_count = specGridLayout->rowCount();
specGridLayout->addWidget(specNameLine, row_count, 0, 0, 0, Qt::AlignLeft);
specGridLayout->addWidget(specTypeLine, row_count, 1, 0, 5, Qt::AlignLeft);
specGridLayout->addWidget(rangeTypeCombo, row_count, 7, 0, 5, Qt::AlignLeft);

@Radio1985
I would start by changing all your row and columns spans which are 0 --- which does not make sense --- to 1?

On a separate matter, are you aware that with the column starts+spans you specify column #6 will be empty?

@JonB
Thanks, yes it works when I change the spans to 1. I get the following. The issue was the row_number starts with 1, even if I don't have added any rows.

Now I have the other issue on aligning them according to the the label positions I have added.
I am not that clear on how the span and positions working.

I modify the addWidget as below:

specGridLayout->addWidget(specNameLine, row_count, 0, 1, 1, Qt::AlignLeft);

 specGridLayout->addWidget(specTypeLine, row_count, 1, 2, 1, Qt::AlignLeft);

 specGridLayout->addWidget(rangeTypeCombo, row_count, 3, 1, 1, Qt::AlignLeft);

Then I get the following results.

I want to align them according to the label on top.

You added spacers in the first row, but you do not do that for the other rows. That's why they do not align.

@jsulm
Is there is away I can add them programmatically?
Thanks!

@Radio1985
I don't understand what exactly is wrong/you want to do from your pictures. Perhaps @jsulm does. But, yes, anything can be added programmatically. In fact if you design to produce a .ui file that gets processed into a ui_....h file with C++ code to implement everything designed. So "everything is programmatic". You can even examine the ui_...h file if you want to see what code is generated, for you to maybe copy and use elsewhere.

Why do you need them? Why don't you simply left align the elements in first row?

@jsulm @JonB ,

Thanks for the suggestions. Yeah I was able to learn from ui_...h file how things are implemented.
I removed all the alignments in the first row. Then I set my dynamic widget parameter dimensions and alignment according to the first row.

Thanks!
