Hiding toolbox results in trapped blocks

[Jing An Tew]

Hi, when hiding the toolbox programmatically through `.getToolbox().setVisible(false);`, the starting block gets trapped (it can't be dragged past the red line), this behavior disappears 

after blocks are added to the starting block, anyone know why this is the case?

Block cannot be dragged past this invisible red line

When blocks are attached, no issue dragging them past the toolbox, removing that block brings the issue back.

Hi, I think the workspace is not used to it's new dimensions.

Whenever you set the Toolbox to invisible and also visible you can call Blockly.svgResize(workspace); 

Then the workspace calculates it's new dimensions to fill the container space completely.

Hi Rico,

Thanks a lot, that seems to have solved the issue.

Hi, an additional question, since showing the toolbox cuts space off the blockly workspace, and hiding it increases the size of the blockly workspace, to give a better user experience, is there a method to call to ensure the blocks remain (visually) at the same position?

I should mention I'm currently trialing scrolling the workspace based off the toolbox width, but it doesn't seem to be working 

Code used when hiding toolbox: `blocklyWorkspace.scroll(blocklyWorkspace.scrollX + <lengthOfToolboxWidth>, 0);`

For some context on what's happening, I have attached a video here, I'm not sure why the scrollX value is changing even though the workspace has not been interacted with in any way.

Hello,

I don't have a solution for your scrolling function but I think it could work if you experiment a bit.

I have my own Toolbox on the right side of the screen with toolboxPosition: 'end' in the blockly inject options. There the effect doesn't happen.

So if you don't care if it's left or right, you can also place it to the right as a workaround.

Hi Rico, thanks for the response. Unfortunately, my toolbox needs to be on the left. Guess it's back to the drawing board. I do find it quite weird that this is happening though. The existing code should work fine.
