Hi!
In Simulink, programmatically determining whether the name of a block is shown on the canvas can be a bit tricky, especially when the 'ShowName' and 'HideAutomaticName' parameters are both set to 'on'. When both options are enabled, the block's name might be automatically shown or hidden based on certain conditions, making it less straightforward to determine its visibility.
To check if the name of a block is displayed on the canvas, you can use the MATLAB API for Simulink. Specifically, you can use the get_param function to retrieve the value of the 'ShowName' and 'HideAutomaticName' parameters for the block in question. Then, based on their values, you can infer if the block name is currently displayed.
Here is the snippet of code that you can refer:
function isNameVisible = isBlockNameVisible(blockPath)
% Get the values of 'ShowName' and 'HideAutomaticName'
showName = get_param(blockPath, 'ShowName');
hideAutoName = get_param(blockPath, 'HideAutomaticName');
% Check if the name is set to show
if strcmp(showName, 'on')
isNameVisible = true;
elseif strcmp(showName, 'off')
% Check if the name is set to hide
isNameVisible = false;
else
% The 'ShowName' parameter is set to automatic, check 'HideAutomaticName'
if strcmp(hideAutoName, 'off')
isNameVisible = true;
else
isNameVisible = false;
end
end
end
