I've got a doubt on calculating window-size-ratio's accordance between panels.
I want to know generally how will they implement this or any useful links or tutorials on this.
I will try to picturise the scenario before you!
Consider there are two Windows Main Window & Child Window Both of these windows extends Panel class
We need to calculate window-size ratio's between these Main Panel & Child Panel!
Main Panels features 1) These main panel is used to represent some time-duration say 10 min or 20 min. It is represented numerically .
But at any point of time the main panel will display 10 time-durations. If we scroll also, it will display 10 time-durations.
2) It has a vertical & horizontal scroll bar to scroll through these time-durations.
3) These main panel implements adjustmentlistener
Child Panel features 1) These child panel represents the main window components i.e. time-duration in rectangular bars.
2) It also has another broader white-color rectangle, which is used to move over these bars whose height we need to calculate. (rectheight)
Generally the 10 time-durations at any time in main panel, should be represented in Child Panel by covering those bars with these white-color rectangle.
Here p.x --> Point.x
p.y ---> Point.y
So now comes the crux of my question.
My child panel has a reference to the main panel, through which it can call the main panel's adjustment-listener's methods. 1) When we vertically scroll the time-duration in Main Window , (say at that time 5-15 time-duration representation) , the corresponding 10 time-durations in ChildPanel (which are represented in bars) should get highlighted in white-color rectangle(which moves over all the bars).
2) Also when I'm moving my white-color-rectangle over the bars in child panel, the corresponding time-duration only should get highlighted(should come in main window) in main panel.
For this size-accordance should be calculated between main panel & child panel right?
How that can be done!
I want to know generally how will they do this or atleast some idea or links is suffice!
