key event

 [1/3] from: hijim::pronet::net at: 8-Jul-2002 18:10


It turns out that remove system/view/screen-face/feel/event-funcs messes up request-file. Is there a way to keep get the caret positiopn whenever any key is pressed? I used the following to get the caret position when I press Escape. key #"^[" [pos: copy system/view/caret] I can then make a button with this code: but "z" [ focus my-area system/view/caret: find my-area/text pos put "Z" 1 ] Now I can reclaim focus and the caret position when I click the button. The put function is: put: func [str num][ if my-area <> system/view/focal-face [return] if not system/view/caret [return] insert system/view/caret str system/view/caret: skip system/view/caret num show my-area ] How can I get [ pos: copy system/view/caret ] to engage whenever any key is pressed? Is there a way? Thanks, Jim

Hi,

view layout [ field feel [ engage: func [f a e][ if e/type = 'key [ print ["key-pressed" e/key] print ["caret" system/view/caret] ] ctx-text/edit/engage f a e ] ] ] --- Ciao Romano

Hello Romano, Thanks for that code. I used it as below to keep track of the lines and to keep the area from ever being dirty. That seems to be the key. It only affects my-area. It doesn't mess with fields or request-file. Finally the buttons always work, and focus stays on my-area -- since it's never dirty! I'm going to try to scroll the slider here too -- on each keystroke. I haven' figured that one out yet. my-area: area para [] 500x490 my-file white white font-name font-fixed wrap feel [ engage: func [f a e][ if e/type = 'key [ get-lines ] ctx-text/edit/engage f a e my-area/dirty?: false ] ] Ciao and thanks, Jim
