Re: [Engine-devel] GUI widget for adding/removing entries

see attached: AFAIK, there are three types of adding-and-removing widget in the application: (1) the one that exists in the customs properties section as well as the cluster policy. in this widget: - the "+" and "-" buttons appear on every row. - row is "identified" by a selected item from a drop down. - input controls in row: drop-down and text box (that appears upon selection of a non-empty value in the drop-down) (2) the one that exists in the vNICs assignment part of the General section in the New VM dialog. in this widget: - the "+" appears only in the last row, "-" appears in all lines but the last row. - row is "identified" by (what seems to be a) read-only label (I assume that this widget is built to be initially loaded to already contain a number of rows, as opposed to (1), which typically starts with no rows / initial "empty" row. - input controls in row: drop-down (3) the one that exists in the vNIC profiles section in the Add/Edit Network dialog in this widget: - the "+" and "-" buttons appear on every row. - row is "identified" by a free-text string. - input controls in row: text-box, check-box and drop-down. so there are differences between the widgets other than the "+" and "-" buttons. however, from ux perspective, it is important to keep the look-and-feel of all of them consistent. technically (code-wise), I am not sure how easy it is to merge the three, due to the differences. we can maybe think of creating a general adding-and-removing-entries widget, which can support "ordered" and "non-ordered" flavors (which will affect the "+"/"-" buttons appearance / exact behavior), and it will contain a collection of "abstract" row-widgets (and we will have several implementations of row-widgets for each needed functionality [(1), (2), (3)] with exact appearance / input controls / behavior/etc.), which may need to support a certain api (e.g. isRowEmpty(), get/set Identifier(), etc.) in order to communicate appropriately with its "parent" adding-and-removing-entries widget. thoughts?
