VCB and Shortcut Keys

Without
enableVCB?you cannot make VCB input...And I've made use of s in VCB input - but it cannot be the first character to be typed.
I am using SketchUp 2013 Pro Windows version. I can comment enableVCB? out and still enter data through the VCB. However, if I enter 5s it invokes the Scale tool. I haven't tried Make or version 8.
In my 2d tools the user can type say12sto change the segmentation of arcs/circles etc just like the native-tools, typing12s+<enter> does NOT invoke the Scale tool in v8 OR v2013...
I have just retested it to make sure.
Perhaps there is something adrift in the way you are making your 'Tool' ?
Do you have it setup and made as a tool-command as required ? -

I cannot reproduce this...
class MyTool; end; Sketchup.active_model.select_tool( MyTool.new )Any chance you've already loaded the code with enableVCB? ? Because then commenting out will not remove it if you reload the file.

Here is the sequence on my Windows PC.
- Comment out the enableVCB? method.
- Open SketchUp.
- Open my model.
- Select my tool.
- Pick first point.
- Type a number into the VCB with no characters.
- Press Enter and the number is interpreted as a length by my conversion code.
I can repeat this sequence with only steps 6 and 7 changed.
6. Type a number followed by t, no space, and the Tape Measure tool come up.
7. Never get to step 7.If I repeat the sequence using s in step 6. instead of t I get a system beep indicating the input can't be parsed (I don't have the code in there to parse an s).
Now I repeat these same three tests with the enableVCB? method coded to return true. Note I completely close SketchUp, make the code change and Re-Open SketchUp. I Don't use reload.
I get exactly the same results as with no enableVCB? method. Further, as I mentioned earlier, if I code the enableVCB? method as follows:
def enableVCB? UI.beep return true endI never get a beep on any keystroke. But I do with left mouse button presses (and I believe left mouse button up as well). There is a bug here someplace but I am not sure how it should work. I know how I would like it to work, but that is probably not interesting to the SketchUp team.
p.s. I get the same behavior on SketchUp Pro 8.
p.p.s. I have a friend who wrote a tool script and never knew about enableVCB? method, hence never implemented it. His tool worked as long as what he typed into the VCB was numbers and no characters. If confirmed for me that he gets the same results I do when he uses a shortcut key. He then implemented the enableVCB? method to return true and also got the same results. -
I'm puzzled that you can get a tool to accept VCB input if enableVCB? is not implemented... did you try my bare bone example?
What Windows version do you have?And I don't think that enableVCB? is meant to be called on each key stroke.

I modified your example as follows:
class MyTool def onUserText(text, view) begin value = text.to_l #just to do something rescue # Error parsing the text UI.beep puts "Cannot convert #{text} to a Length" value = nil Sketchup::set_status_text "", SB_VCB_VALUE end return if !value UI.messagebox(text) end end; Sketchup.active_model.select_tool( MyTool.new )I typed 36 into the VCB and hit Enter. Resulting output is shown in image at bottom.

Windows 8 64 bit.

Well, if it is supposed to allow and check for accepted characters besides numerals I would think it would have to. But it should at least be called on Enter and it isn't.
-
@tig said:
The excepted characters that are OK after a number are:
",',m,mm,cm,s,x,/,*,[,],<,> etc
Can you use some of those in your custom inputs...TIG,
Where in the documentation did you find this list of accepted characters after a numeral? I haven't been able to locate it.
-
It doesn't exist...
Just made it up - from what I know works...
-
That's interesting. Just making use of onUserText will enable the VCB - making enableVCB? redundant. (Though this might need testing on all versions - in case this is something that has changed.)
I don't see the point of enableVCB? if onUserText automatically enables it...@chiefwoodworker said:

It's only a simple property to enable or disable the VCB.
The docs only says:The enableVCB? method is used to tell SketchUp whether to allow the user to enter text into the VCB (value control box, aka the "measurements" panel). If you do not implement this method, then the vcb is disabled by default.So it doesn't affect what types of characters you can input - it just enables/disables the control as a whole.
But I agree that there should be a way to prevent keyboard shortcuts from triggering.

I don't think it is the onUserText that is enabling the VCB. I think the default is true, not false. Try this script:
class MyTool def enableVCB? UI.beep end end; Sketchup.active_model.select_tool( MyTool.new )Depress and release the left mouse button slowly. You will see that enableVCB? is called on both the down and up of the left mouse button. That's why I think it is intended to sample each key stroke, to see if a shortcut key was preceded by a number, in which case it would be interpreted as a parameter of the number and not a shortcut key. But it doesn't get called at all with a key stroke, including the Enter key, which I think is the bug. Why is it called with a mouse action? That's what's curious to me.
-
I asked the SketchUp team, and they confirmed that onUserText enables the VCB - and enableVCB? is there to let you disable the VCB when you do not want user input. (For instance - if your tool uses the VCB to adjust values then you don't want the VCB to be enabled until you have performed an action.)
And enableVCB? is queried on certain event which one can assume the tool changes state - such as on mouse clicks.

I looked further at the behaviour of the Tool class - using variations of this snippet to inspect the behaviour:

Here's a quick summary of which event triggered which was followed by enableVCB?:
` activate
enableVCB?onMouseEnter
onMouseLeave
onLButtonDown
enableVCB?onLButtonUp
enableVCB?onLButtonDoubleClick
enableVCB?onMButtonDown
onMButtonUp
onRButtonDown
enableVCB?onRButtonUp
onRButtonDoubleClick
onKeyDown
onKeyUp
onUserText
onReturn
enableVCB?`The event's that responded with enableVCB? query:
activate onLButtonDown onLButtonUp onLButtonDoubleClick onRButtonDown onReturnOther observations:
IfonKeyDownoronKeyUpreturntruethen no text is entered into the VCB. It appear to block it.When the VCB is enabled: Space, S, M, K etc didn't trigger it's shortcuts - but only if I had typed a number first.
If the VCB is enabled, and you enter some input to the VCB then first
onUserTextwill trigger the first time you hit Return - then on the second you hit ReturnonReturnwill trigger.If the VCB is disabled then
onReturnwill trigger every time you hit Return. -

thomthom,
Thanks very much for the help on this and clearing things up. The documentation on this is really poor and misleading. I still wish we had a way to disable shortcut keys like the native tools have.
Thanks again.

thomthom,
Your help is well above and beyond anything I could ask for. Thanks again. I am loading the snippet to complete the "etc" and see if there are keys I can use.

Hi Joe,
your script partially works on mac withto_fadded @ line 4.
a lot of Capitals work as well, e.g LBWH all work, as a block or on their own...value = text.to_f.to_l #<<ADDED TO FLOATjohn

Text is a String class.
Value is a Length class.But your code is clearly more correct and you may have saved me a Mac bug. Very interesting that it works on the PC but not the Mac.

Whoops! Let me correct myself. SketchUp has a String def called to_l so the you don't need the to_f. Are you sure it doesn't work without the to_f?
-
with your original code, I get
Cannot convert 1w to a Length
if I change only this linevalue = text.to_f.to_l #just to do somethingI get 1w in the message box...
with your last code I get an empty message box, with or without the

Why not take your normal 'numbers' text as your lengths, and then use key-down checks for toggling what it means ?
Like Cmd/Ctrl, Shift etc *** - so on one press of that key it expects one type of value [shown in status-bar] on the next press it's something else = i.e. it's a 'toggle'.***You can use TAB key action as a toggle BUT it must be key-up as the MAC doesn't recognize tab-down - only tab-up !
