Maximized the main form

Recommended Posts

Hi, I have this little problem: when I want to maximize my application the height don't care of the main task bar of windows; the height of my application is the height of the screen including the task bar.

Anyone have this problem or anyone know how to fix it?

Thanks.

Hi Roberto,

 

In the OnConstrainedResize event of the Form include the following:


MaxHeight:= Screen.WorkAreaHeight;
MaxWidth:= Screen.WorkAreaWidth;
 

This works for me. I have only 1 monitor, so I don't know how well it works in a multiple monitor setup.

 

Greetings,

Fons

This should not be necessary. It also seems like there would be scenarios which this would stop the user doing things they want to do.

Does this happen with a brand new VCL app with a single form that does nothing? If not then the answer is specific to your code.

Hi David,

 

With a vanilla VCL application it is not required. I use the TMS FNC Ribbon and when maximized it covers the Windows task bar.

In the Delphi Designer it looks like this.

When I run the application it looks like this. This is right after using the New Item template which creates a new application and form. I did not change a single thing.

Unfortunately, when maximized it covers the Windows task bar. Programming is just a hobby for me, though I do make application that are used at work (my job however has nothing to do with programming). The easiest way to fix it, was using the OnConstrainedResize event. I am not a bad Delphi programmer, just as long as it is standard Delphi code and not all kinds of trickery with Windows handles and such things.

 

I will report this to TMS Software. For the record, I use Delphi Pro 11.1 with patch 1. 

 

My simple solution for now works with 1 monitor. At work we use 2 or more. My solution probably has unwanted effects when using a multiple monitor setup. Not sure, but probably.

 

So, unless TMS fixes this, I will need some kind of workaround. The last resort option is to prevent the application from maximizing.

Hi David,

 

I reported it to TMS. They provided a solution. However, I finally decided to base my main form on the standard TForm and not TTMSFNCRibbonForm. 

 

This of course had some impact on the visual side of how the form looks, but I am okay with the end result. Now, maximizing the form works as excepted without any tinkering. Also, as a benefit when the user changes the width of the form with the mouse, the ribbon does not flicker anymore.

MaxWidth:= Screen.WorkAreaWidth;

You could use the Constraints property of the form instead of using the Event.

 

Self.Constraints.MaxHeight := Screen.WorkAreaHeight;
Self.Constraints.MaxWidth := Screen.WorkAreaWidth;
