Toggle between form and unit is not working in Firemonkey project

Question

I'm testing Delphi XE2 and I create a new FireMonkey HD Application, but I have an issue the form designer for the FireMonkey forms is not visible or Available, the option Toggle Form/unit in the View menu is disabled as well the toolbar button to switch between forms and code, even using F12 does not work. I tried the Shitf-F12 option (Forms windows) but none form is listed. I tried adding new firemonkey forms too, but none form is shown, only the code is visible. -Any suggestion to solve this issue?

Answer 1

I had the same issue some days ago and the problem was that I disabled the Embedded designer option. So it seems that the FireMonkey form designer only works in a embedded window.

Try enabling Embedded designer option in

Tools -> Options -> Environment Options -> VCL Designer -> Embedded designer

For information this is written in the readme:

FireMonkey Requires Embedded Designer

FireMonkey only supports the embedded form designer. If the IDE is set to use the non-embedded designer (that is, if Tools > Options > Environment Options > VCL Designer > Embedded Designer is unchecked), then FireMonkey projects will open FireMonkey Form units as if they were plain Delphi units. The Form Designer will not be accessible. To use the Form Designer, check the option to use the Embedded Designer and restart the IDE.
