In Poland, exists such a proverb:

Thanks.

HMG is so simple and has much space for work-around.

Hello Rathi!
I'm backink to this topic, because of some reason.
Once drawed graph is destroyed by another controls localized on another tabs.

I've modified above sample.
Please, compile and test.

Code: Select all

# include "minigui.ch"

function main
define window sample at 0,0 width 1000 height 700 main
   define button pressme
      row 10
      col 10
      width 80
      caption "Press Me!"
      action docustomprogressbars()
   end button
   define tab t1 at 50,5 width 900 height 520 on change checkgraph()
      define page "Page 1"
            DEFINE BUTTON P_Zlecenia
                ROW    50
                COL    30
                WIDTH  500
                HEIGHT 400
                ACTION {MsgBox("Please check your graph!!! I'm switching TAB..."), sample.t1.value:=2}
                CAPTION "Anything I want to put in another tab destroys good look of my progress bars!!!" 
                FONTNAME "Arial"

I think, graph is redrawed too early. But, I don't know where to put function to refresh graph

[Rathinagiri]

Thanks Marek. I will check it out.

Reading bug reported by Grigori Filatov, I've found so simple solution of my old problem - how to build simple graph in the window...
I wanna share my solution.
Please do not laugh at me
but I think, simple solutions are the best!

[Rathinagiri]

Ha ha.

Nice one Marek.

[mol]

Thx, Rathi

Hi Marek! I tested your SimpleGraph. Some funny-looked... but very good idea and simplest code It's really useful! I'll think: where I can add this (into my apps)?

[mol]

I think, it could be very useful, when you can use it as progressbar in situation, when you need to change color of bar depending on value - color changing works with original progressbar in win'xp only when windows themes are off. When your turn them on, the color definitions are taken from windows settings, not from your app.
