Boolean Text Position

Shijie — Wed, 15 Feb 2017 15:19:40 GMT

When the attached VI starts to run, the front panel comes right away. The Boolean text position for the Boolean Control is from default position to the position I specified by using Property Node. There is a delay. Is there any way I can set a default Boolean text position? Or use other ways, so that we will not see the delay.

Make your front panel invisible at the begining. After you done with boolean text positioning, make FP visible.

Right click on the control and go to advanced -> customize. Then you can click the little wrench and edit your control. In this mode you can move the text wherever you want and it will stay.

Hi George,

I am new to Labview. I know how to make individual control visible, invisible. But I do not know how to make the whole front panel visible, invisible? Can you tell me how?

Thank you very much,

Steve

With your VI in edit mode, on the front panel, if your boolean text is locked in the center, right-click on it and select "Release Text".

Now you can click on the text and move it to anyplace you want.

Hi BowenM,

I have 24 Boolean controls in the same front panel. If I use the way you suggested, I have to save 24 Boolean controls. I tried to save one control as Type Definition, and other controls use the same Type Definition. But it does not work.

Thank you,

Steve

You don't need to save the control to file... you can just it on the front panel.

As for type definition, make it a "Strict Typedef" and then visual changes will be pushed to all instances of that control.

Hi Paul,

The problem is that the development screen and the target screen does not match perfectly. Each time I compile the file, and intall it into target, the Boolean text position might change. That is why I have to use Property Node.

Thank you,

Steve

Why would the boolean text change position?

There are two ways I can think of.

1. The text is based on a windows symbolic font, like "dialog font". Where on one PC, Windows defines it as Tahoma 8, another PC defines it as Segoe 9. So size and position would change. To solve that, make sure your default fonts in LabVIEW and the controls are all set for a specific font such as Tahoma 8, and not some symbolic font such as "Application" or "Dialog".

2. You have scaling turned on in the VI so things scale and change positions as a function of Window size or resolution. If so, just don't. Design your VI to screen and window size you want, and don't mess with automatic scaling.

Hi RavensFan,

The first suggestion helps me a lot. Thank you very much.

Unfortunately, when my application runs, it has to occupy full screen and it does not allowed to show window title bar, menu bar, scroll bar... except my own menu. Therefore, I have to use automtic scaling (Scale all objects on front panel as the window resizes). It does cause me a lot of work. Right now, I do not know how to get around it.

Thank you very much again for your help,

Steve

Don't use automatic scaling. It doesn't work well and is very difficult to make it so it works right.

Are you trying to make this work on one specific screen or make it adaptable to multiple different screens that have multiple different resolutions.

Just develop your VI so that it is full screen and none of those bars and menus show except for your own. If your window has to be full size, then you shouldn't have to worry about a window resizing!

Semi related- if I have 4 Booleans but want 3 to be made false if one is made true ... how would I set that up?

I fiddled with case structure and logical operators but can't get anywhere

Not really related at all.

What you are talking about are called radio buttons. They are on the boolean palette.
