Node text doesn't appear if node-text width is more than node width. (Read 3075 times)

	Hi, I am creating one node with following snippet of code. node: TableNode = this.diagram.getFactory().createTableNode(110, 80, 55, 30); node.redimTable(0, 0); node.setEnableStyledText(true); node.setText('This is the node whose node text is not getting wrapped') node.resizeToFitText(false, true); Initially the node text doesn't appear, But when we increase the size of the node it appears. I think its because we have width of node is less than the node text width. As per the requirement we need fix width of the node. I think after wrapping of the node text this will get resolved but i am not able to achieve wrapping of the node text with the above snippet of code. Even though the same code works for cell text wrapping. Can you please let me know how can we solve this issue?

	Hi, Apparently the resize method returns directly if table is empty. Try something like this for time being - Code node.redimTable(1, 1); node.resizeToFitText(false, true); node.redimTable(0, 0); Regards, Slavcho Mindfusion

	Hi, It worked but now i am facing issue with node structure. We need to split node between caption and row by default. But now after this change the node changed with no split. Please find attached image.

	Try this method Code function fitTextEmptyTable(table, maxWidth, cellAreaHeight) { var padding = table.getTextPadding(); var diagram = table.parent; var layoutRect = new Rect( 0, 0, maxWidth - padding.width(), Number.MAX_VALUE); var captionSize = diagram.measureString( table.getText(), table.getEffectiveFont(), layoutRect, table.getEnableStyledText()); table.setCaptionHeight( captionSize.height + padding.height()); var bounds = table.getBounds().clone(); bounds.width = captionSize.width; bounds.height = table.getCaptionHeight() + cellAreaHeight; table.setBounds(bounds); }

	Hi, In the above example fitTextEmptyTable(table, maxWidth, cellAreaHeight) table represents "node" and cellAreaHeight represents "node.getCell(1,1)" is it correct? If yes i'm not able to find cellAreaHeight of cell. if not please let me know what is represents. Even though tried with hardcoded values e.g. fitTextEmptyTable(node, 55, 30), but its not working.

	The above was assuming you run it on empty table with 0 x 0 cols and rows as in your original code, and the height argument is how much space you want to leave for the empty space. If you want it to work for a 1 x 1 table, you will need to assign that value to the height field of the (only) row object.
