MATLAB: How to promote type selection popup to subsystem mask

masked subsystempromote parameters

I am using Altera DSP Builder with Simulink and I want to create a masked subsystem that contains the library block "SampleDelay". The SampleDelay block has an output type that is set by a popup where you can select the type to be inherited or specified by a dialog. How can I promote this popup with all the options to the subsystem mask so that the SampleDelay output type can be set from the subsystem mask?

Solved this by following the examples in the "Dynamic Mask Dialog Box" help section.

More specifically, I needed to promote both the output mode (popup) and the output type/scaling to the mask. Then the visibility of the output type and scaling can be controlled in the callback function of the output mode as described in the help text.

Parameters of blocks located inside the masked subsystem can be modified from the Mask dialog box by having it 'promoted' to the mask. Please refer to the link for further information on promoted mask parameters:

MATLAB: Promote parameter and add it to tab programatically

The 2017 documentation is incomplete and fail to provide the actual way of doing it.

The 2014b documentation however is complete. Here is what is missing:

    6 - Move the mask parameters you created previously to the first tab.
    opt1 = maskobj.getDialogControl('option1');
    opt2 = maskobj.getDialogControl('option2');
    opt1.moveTo(tab1);
    opt2.moveTo(tab1);

I am also giving you an MWE with an edit field and a popup:

block = 'Untitled1/Atomic Subsystem';
wMask = Simulink.Mask.get(block);
if ~isempty(wMask)
    wMask.delete();
end
wMask = Simulink.Mask.create(block);
wMask.addDialogControl('tabcontainer','tabContainer');
wTabContainer = wMask.getDialogControl('tabContainer');
wTab1 = wTabContainer.addDialogControl('tab', 'Tab1');
wTab2 = wTabContainer.addDialogControl('tab', 'Tab2');
wTab1.Prompt = 'Programatically added tab1';
wTab2.Prompt = 'Programatically added tab2';
wTextOnFirst            = wTab1.addDialogControl('text', 'textOnFirst');
wTextOnFirst.Prompt     = 'Some text on the first tab';
wTextOnSecond           = wTab2.addDialogControl('text', 'textOnSecond');
wTextOnSecond.Prompt    = 'Some text on the first tab';
wField = wMask.addParameter('Name', 'TextField' ...
    , 'Type', 'edit'...
    , 'Prompt', 'Programatically added text field'...
    , 'Value', 'Toto'...
    , 'Evaluate', 'on'...
    , 'Tunable', 'off'...
    , 'Enabled', 'on'...
    , 'Visible', 'on'...
    , 'Callback', 'disp( get_param(gcb, ''TextField''))');
wPopup = wMask.addParameter('Name', 'PopupField' ...
    , 'Type', 'popup'...
    , 'Prompt', 'Programatically added popup field'...
    , 'TypeOptions', {'Value1', 'Value2', 'Value3'}...
    , 'Evaluate', 'on'...
    , 'Tunable', 'off'...
    , 'Enabled', 'on'...
    , 'Visible', 'on'...
    , 'Callback', 'disp( get_param(gcb, ''PopupField''))');
wFieldDialog = wMask.getDialogControl('TextField');
wPopupDialog = wMask.getDialogControl('PopupField');
wFieldDialog.moveTo(wTab1);
wPopupDialog.moveTo(wTab2);
