Posted: Tue Mar 27, 2018 11:45 pm Post subject: Resizing different %gr areas in the same window |
|
|
Hi,
I am experiencing a problem with my application; I am using a single window (%ww) with three different %gr areas in the window,
rslt=winio@('%ww%ca[FLUXOVIZ]&')
rslt=winio@('%1.2ob[raised]&')
rslt=winio@('%cn%ws%nl&','Painel de Controle')
rslt=winio@('%`^gr[black,rgb_colours]&',painel%xmax-painel%xmin+1,painel%ymax-painel%ymin+1,&
id_painel_de_situacao,painel_de_situacao)
rslt=winio@('%cb&')
rslt=winio@('%`gr[white,rgb_colours]&', &
barra_cores%xmax-barra_cores%xmin+1,barra_cores%ymax-barra_cores%ymin+1,&
id_barra_cores)
rslt=winio@('%cb&')
rslt=winio@('%ob[no_border]&')
rslt=winio@('%`^gr[black,rgb_colours,full_mouse_input,box_selection]&', &
tela%xmax-tela%xmin+1,tela%ymax-tela%ymin+1,&
id_tela,trata_mouse)
rslt=winio@('%cb&')
rslt=winio@('%lw',janela_principal)
and would like to resize the one highlighted above, but if a use a %pv and the option user_resize, when I resize the window, the other two graphics areas move out of place...
I prefer to use three graphics areas since I can keep coordinates which are unique to each and can just select the desired graphics region...
Cheers

you could set up an MDI (multi-document interface) window and define several different fixed size child windows within it and put each %gr graphics window in seperate child windows.
Thus the child windows remain unchanged while the &gr can be re-sized individually within each one without affecting the others. _________________ ''Computers (HAL and MARVIN excepted) are incredibly rigid.

I suggest that you post a simple and complete program that illustrates what you want to do. Then others can try out different strategies.
The best answer might be to do the resizing via the new design mode (which I plan to demonstrate on Youtube shortly). This provides an alternative resizing method that might do what you want.
p.s. "shortly" = about two weeks. |

If you have 3 %gr areas, then you have separate coordinate systems for each, and a different callback for each, but it is much easier to keep it all in one %gr, and simply work out which one you are ina at any time. For example, if you have 3 pseudo %gr field all top aligned, your callback only has to test for the x coordinate (and so on).
Doing things in one %gr also makes the division bars movable independently, for example with 2 areas top aligned and one below them taking the full width, then you can test the pixel position and if you are in the horizontal bar you can change the cursor to arrange resizing vertically, or do the same with the vertical bar.If nice cursors aren't already in Windows/Clearwin+, there are plenty downloadable on the web. I sometimes use the 'smooth' cursors by Vlastimil Miler - they're excellent.

Rudnei,
It's good that you've put together a test progam but after running it I'm still not sure exactly what you're tryng to do.
Are you actually trying to keep a fixed-size overall window and just be able to change the size of the bigger graphics area (which was my understanding from what you wrote at the top of the post) ?
In the example that you've posted it's odd because the left hand %gr 's are 'fixed' to the bottom of the window while the larger one with the circles which re-sizes is the inverse, fixed to the top of the window - so it's like 2 ships crossing in the night - as you pull down the edge of the window the larger %gr comes down while the top of the left hand areas 'slide' off the top of the window.
I still think the use of mdi with the main window, then defining a frame, then defining 2 child windows, the one on the left containing the 2 smaller %gr 's and the one on the right containing the larger one made re-sizeable along with the %gr itself re-sizeable, will probaby work.
A couple of other observations in passing, these actions (except the first one which may be a bug or a result of some specific combination of actions) may be intentional and/or just a function of having created a test program but I mention them here just for your information in case they're unintended actions :-
1. Try maximising the window first, then move it using the caption bar ..... and the window size changes (reduces) !!! Very odd behaviour.
2. the behaviour of the mouse actions in the circles window seems a bit odd. If I select a region I intuitively expect it to enlarge so that only that area then fills the %gr area. Is that what you intended ? because it actually reduces it and sends it into the top left corner of the screen.
3. after doing as in 2, if I click with the right button in the graphics area the graphics become larger, but not to the same size as the priginal, nor do they fill the screen.
4. After right -clicking, try clicking left button and the 3 circles disappear ! _________________ ''Computers (HAL and MARVIN excepted) are incredibly rigid. They question nothing.

Dear John,
Thanks for your reply. Indeed this sample have some side-effects from trimming the actual code, as you have pointed out; item 1 specifically I have no idea at all since the only control I have is via the event GRAPHICS_RESIZING...
But the main thing is: how do I create this MDI? I don't have Visual Studio available... can I do it directly with ClearWin+ ?
Cheers

Hi Rudnei,
yes it's created with Clearwin+.
We need to know exactly what you are trying to sìachive which is why I asked
Quote: | Are you actually trying to keep a fixed-size overall window and just be able to change the size of the bigger graphics area (which was my understanding from what you wrote at the top of the post) ? |
... or something else ?
If yo uclarify that I'll take a look.
You can get an idea of the MDI concept here in the working code posted on 9th April.here
http://forums.silverfrost.com/viewtopic.php?t=3746
That's a simple example with a single window nested inside a frame which is defined in the main window.
It's all about working out the nesting strategy you ned and then specifying which sub-window (child-window(s) need to be pivoted so that they re-size automatically when the parent window is re-sized with the cursor. _________________ ''Computers (HAL and MARVIN excepted) are incredibly rigid.

Dear John,
I have been looking into the last code provided in the topic you mentioned.
Looks like it will do the trick; I'll try with my application and get back to you.
Cheers!

Hi John,
I have modified the code supplied in the aforementioned topic; however, the window captioned "Simulation" is not resizable... any ideas on how to do it?

I hear in my Antarctica how you guys are swearing trying to tame this wild horse called Clearwin. Even i did when tried to fix, did you hear my french? Company must make 100000 demo examples, not 10-15 like all these 20 years. Here are all 4 windows resizable (added text window), "rgb_colours" are now redundant, %es (Escape key) makes debug easier.
