[code] Win32 Moving/Showing/Hiding Toolbars and Dialogs

thomthom

hm....

The WS_EX_NOACTIVATE value for dwExStyle prevents foreground activation by the system. To prevent queue activation when the user clicks on the window, you must process the WM_MOUSEACTIVATE message appropriately. To bring the window to the foreground or to activate it programmatically, use SetForegroundWindow or SetActiveWindow. Returning FALSE to WM_NCACTIVATE prevents the window from losing queue activation. However, the return value is ignored at activation time.

"queue activation"?

thomthom

bleh... turns out to not be so straight forwards as I though. Seems that one needs to handle some window messages:

http://stackoverflow.com/questions/2969680/c-showing-form-with-ws-ex-noactivate-flag

But working out how to handle window messages would be a very interesting thing - as then we could recreate the roll-up/down feature of SU's toolwindows.

tt, most of this discussion is "over my head", but will the result permit toolbars to unfold perpendicular to the edge of a sketchup window like the menus do? If so please provide a simple version that we can use to compact our application toolbars.

thomthom

It doesn't modify existing toolbars. I'm simply modifying the appearance of webdialogs.

You mean toolbars where you click on a button and it displays a dropdown list of more buttons?

honoluludesktop

Yes, Would go a long way to cleaning up our screens.

thomthom

Interesting though - but I'm not sure if it's possible. In either case - if you start making all toolbars like that they end up having the same problem as menus - that everything is hidden in sub-menus and you need an extra operation to reveal it - to be able to explore available commands. I feel the usability would not be improved.

If one has that many toolbars open I'd rather ask if they are all required to be there on screen.

Personally I assign hotkeys to the most frequent commands I use. Then I have a few toolbars for semi-frequent command. For everything else I use the menus.

I have been toying with the idea of having a webdialog which allows you to filter out the commands you want - and make sets of tools you can switch between depending on the job.

You are probably right about this.

thomthom

I do have an experimental hack to catch all menus, commands and toolbar items that's created. I hope to tind time soon to put together a basic version of a plugin that let you quickly search and filter out available commands.

These are called "Flyout Toolbars" and have been a part of the AutoCAD GUI since at least R13 (circa 1994) and perhaps even R12 in Win16 mode.

This is one of the things on my to do list for Win32 Sketchup.

Just came across a nice API call that will be useful for creating webdialog toolbars:

One can use WS_EX_NOACTIVATE to prevent a window from catching focus - but from what I understand it'll still allow interaction events. I'll try it out as soon as I get home.

Just had a go at this. I could not get a webdialog to not get any focus when I set WS_EX_NOACTIVATE - but I could make a Notepad window to change. I don't understand why.
When I check the EX_STYLES of the webdialog the WS_EX_NOACTIVATE bits appear to be set.

Dan Rathbun

WebDialogs are child windows of the SU app window.

The Notepad window is a toplevel window.

thomthom

Does that matter?
Floating toolbars are also child of the SU window...

Well.. you you didnt understand why...
I propose the flag acts differently for child windows versus toplevel windows.

.. it's the only difference I can see at first glance.

thomthom

Yea, I was looking at that myself, but when comparing to the floating toolbars I could not see any significant difference. But I'm not that familiar with Win32 API.

hi Thomas,

been trying to make a 'nice' Mac toolbar in a WebDialog, and discovered that if you hold down the cmd key (i.e. before clicking the tool icon) you don't move focus and the tool (and cursor image) is there immediately on mouse-out.
This is one click LESS than on a standard mac SU toolbar icons as I don't have to click back into the model space to activate the cursor.... (command clicking SU toolbar icons does the same thing, as well)
so, question is, do you have a snippet that will send a cmd_key_down on mouse-over of the WD?

Are you saying that clicking a native toolbar button in SU steals focus from the main window? (I need to unpack my Mac from my moving-boxes to have a look at this.)

I've never developed for OSX - so this is unknown territory for me. But will you even be able to receive mouse events if the window haven't got focus?

NO, sorry, I just rechecked, I've got 'standard' icons in WebDialogs that I'm doing tests with, they behave the same as 'ruby' icons in the same WD...

standard toolbars DO NOT highlight the box or such, and DO an instant tool-change,

unlike

the standard WD which requires
1st click on dialog to highlight/focus box
2nd click on icon to select manipulation tools or send action direct (undo, redo, etc...)
3rd click on drawing space to reveal cursor (and select first point) if manipulation tool

unless
you hold down the cmd key before clicking....

the WebDialog then behalves the same as 'standard' toolbar, and you can also change tabs, access drop-down menus, select tools etc... all without drawing focus away from drawing window... but you have to hold the cmd key the whole time...

if the web dialog sent a function call to hold the cmd key down on mouse-over, then you'd have a useful tool window...

hope that clarifies what I'm asking/saying/thinking.....

clear as mud

Understood.

This OSX behaviour of dealing with windows is causing my little greys to twitch in pain - my BezierSurface plugin was suppose to use WebDialog toolbars and windows extensively. Now I need to find a way to handle this or scrap the UI (which I've written a great part of the framework of already and find a new solution.)

I've been searching for ways to manipulate windows under OSX like one can do under Windows with the Win32 API - but I never find anything.

Thom,

I just did a scan of the different windows used in SU, what features do you want enabled/disabled in your WebDialogs?

I'm having a look at UI.Browser.app to see if I can use that to tweak SU windows...
