How to change Horizontal size of a Constant block based on the "Value" of the block in order to make the value visible

If block size is small, constant value is not visible, it shows the value as -C-. To avoid this -c-, i need to control the size based on the value programmatically.

You have to use the command: set_param(Block,'Position',[50 100 80 130])

But I don't know how to dectect if the value is played on the block or if it is "-C-" which is displayed...

If -C- is displayed, i need to change the Horizontal size according the value of the CONSTANT block. For eg. if the parameter value is "abc", width can be 40 PX. if it has "ASDFGHJKL" width should be high in order to display the whole value in simulink model instead of displaying -C-.

If you don't want to change the position of your block. Get it's actual position

pos=get_param('ModelName/Constant','Position');

Then just change the coordinate pos(3) and pos(4)

set_param('ModelName/Constant','Position' ,[pos(1:2) pos(3)+30,pos(4)+60])

My intention is to make the value visible in simulink model. If -C- is displayed, i need to change the Horizontal size according the value of the CONSTANT block. For eg. if the parameter value is "abc", width can be 40 PX. if it has "ASDFGHJKL" width should be high in order to display the whole value in simulink model instead of displaying -C-.

I understand what you want to do. And the command line that Abdelmalek and I provide you allows to resize a block. So you just have to create an algorithm which allow to detect if "-C-" is displayed on the block and if it is true, you resize this block with the command line.

[THAVAMANI]

Yeah. Thats an good idea. May I know how to detect the "-C-" through script ?
