EasyTab attribute

[lvrat]

Is there a way to gray out the tab? 

If I use ATTR_EASY_TAB_VISIBLE then the tab cannot be displayed at all.

I am looking to make it grayed out so that when tab is selected the controls can be seen but in grayed out mode.

Thanks.

I don't think so, see http://zone.ni.com/reference/en-XX/help/370051H-01/toolslib/listofeasytabattrs/

So may be this could be a good reason to upgrade to native tab controls - these do allow being dimmed (I am actually using this feature)

[lvrat]

Easy tab has a dimmed attribute and so does native tab (ATTR_DIMMED).

What I can't see is a way to gray out.

In other words if the tab gets dimmed it does not even get selected.

I am hoping to select the dimmed tab and display the last values on the control.

Hi Ivrat,

that's my understanding of a dimmed control - it is greyed out and can not be selected. I am afraid that I do not understand how to 'grey out' any control without dimming it... Now it's me who is asking the questions

It appears that the easy tab attributes have changed... in CVI 2010 I found a different list than the one I have referenced, including ATTR_EASY_TAB_DIMMED.

ATTR_EASY_TAB_DIMMED is present in the instrument at least from CVI7.1 on (I cannot test on earlier versions). The problem is that there is a different behaviour between the EasyTab control and native Tab control: a dimmed tab cannot be shown in the former while it shows in the native control, even though all controls cannot be operated.

After some test, I found that you can call SetPanelAttribute on a given tab page with ATTR_DIMMED attribute after the EasyTab is created: the behaviour is similar to the native control (i.d. the tab page can be selected and shown with all controls dimmed).

As a last suggestion to lvrat, since he appears to be working on a recent CVI version, I would reccommend to switch from the EasyTab to a native tab control: from the user point there is no real difference between them. On the programmer side, instead of LoadPanel (the panel with canvas)+LoadPanel (the tab panels)+EasyTab_ConvertFromCanvas+EasyTab_AddPanels (or LoadPanel+EasyTab_ConvertFromCanvas+EasyTab_LoadPanels) he will only have to load the panel and set a series of GetPanelHandleFromTabPage if he needs to save handles.

Thanks all for the inputs:)

Thanks Roberto, using SetPanelAttribute does work as needed.

I am actually using CVI 8.5, should have mentioned that. Nost sure if the suggestion still applies to 8.5?

[RobertoBozzolo]

Native tab control was introduced in CVI 8.0 so you can use it in 8.5: you should find that control in the list of available controls you see right-clicking on a empty panel.

Thanks Roberto, that helped.
