In pgModeler, the majority of forms runs in a modal way which means that if you open a dialog after another you can't reach the previous one without closing the currently active. In some cases, this feature can make the creation of objects a bit cumbersome, where the user needs to create the dependencies first before the object itself. Fortunately, pgModeler implements a workaround that allows the user to create a dependency object from within the editing form of the object being created currently, without the need to close it to access the editing form of the dependency.
Let's suppose that we are creating a new table that contains a new column that will need a sequence object for auto-incremented values. In that case, from the table's editing form we are able to call the column editing form. In that dialog, we don't have any explicit action the create the sequence to be used, it's only possible to select a previously defined sequence in the object picker associated with the
Sequence radio button. If we click the input field in the object picker or hit the action the objects tree will be displayed so we can select the desired sequence. Since there are no sequences available to select, we can easily start to create one by right-click the group
Sequence (0) and select
New sequence. After this step, the sequence creation form will be displayed and you can create the sequence. Once closed the dialog, the new sequence will be automatically selected in the objects tree. Now, just hit
Enter to associate the newly created sequence to the column being created.
