Tab control page label change color programmatically
Hi everybody!
I have a question about a tab control.
I'm trying to figure out a way to programmatically change the properties of the tab labels so the selected tab's label looks different to the others.
I'd like to do this by changing aspects of it's font and it's color. But I can't find out how to access it either directly or by reference.
I can get at the label string so if all else fails I could make the selected one all capitals!
Am I missing something, or is this one of those things which can't be done?
I'm using Labview 11.
Regards,
Jonathan.
The link still works for me!
Search the forum for "Tab Color".
This does not change the text, but the tab color which is what I do to high light the selected tab.
I use dark gray and light gray to help the user tell which tab is "active".
Not exactly what you wanted.

How do i set tab control page size programmatically?
Hi,
I have a tab control in my program and each page has different amounts of controls on it. I would like to know how I can make the tab control pages resize automatically, only to fit the controls on the page and not have extra space underneath that other pages require.romulus wrote in message news:<[email protected]>...

You can use the tab control property 'PaneDimension' to
programatically change the size of the tab control. To
programatically find the areas occupied by the controls on each page:
Use the 'Pages' property of the tab control to get a reference to the
desired page; wire that to a property node and select the
'ControlsOnPage[]' property; iterate through all the control
refere
nces, getting the position and bounds of each control, using
'Max & Min' and shift registers to find the extent occupied by the
controls.

Cannot drag an indicator off a tab control page
I inherit this VI and try to change certain controls in the tab control pages. But the controls are locked together, every time I select an item on the control, everything is selected. And when I make a new string indicator and drop onto the page, I cannot select or delete it. also when I use the arrow down key to move a control onto the tab control page, it does not have a normal shadowed effect to indicate that it's a floating control.
The tab control is in the attachment.

Array of Tab Control page names
Hi,
I wish to programatically create an array of the names of the pages within a Tab Control.
See the attached VI for my attempt at this.
It works, but as it runs it changes which page is displayed on the front panel.
Is there a way to do this without changing the page displayed on the front panel?
Cheers,
Dan

Are indicators updated on an inactive tab control page
To decrease loop execution speed (increase acquisition speed) I have placed diagnostic displays on a seperate tab control page which is normally not the active page. The thought is that speed will be increased as these displays would not be updated unless needed (screen I/O is normally time consumming).
Is this a viable method?
RoyIt is not that those controls will not be updated, but the drawing of
those controls on the screen that you save. This can definitely be very
significant. It is also good programming praxis to hide unnecesary
front panel elements.
Also keep in mind that the eye can only handle 10-20 updates a second,
and even that is for most controls much too fast. Lowering the
indicator update rate to, say, 5-10 times a second, can already
achieve major CPU relief. depending on the kind of interfacing I
would go to much slower updates still. If you use big data sets,
you should also try to prevent creating too many copies in memory. -
Change tab control page programatically using boolean.
I am wondering if there is a way to programatically change the tabs on tab control when a user clicks a button on the interface? Here is what I am trying to do and if anybody has any great ideas please let me know. I have a tab control with currently 3 tabs. I want a button on the main area of the vi to go to page 2 and back to page 1 as the user clicks it. The second is that I want about 5 buttons in page 2 that will go to say page 3-5. Any ideas. Thanks

[email protected]Sure, though I don't know why the user can't just click the tabs themselves. All you need is a simple event structure and writing to a local variable of the tab control.

Tab control page Setting problem?
Why I am not able to change the page Label name programmatically. Why the page Label Name property is only readable?
Hello.
If using Labview 7, you must be able to change tab labels programmatically. There is an example called "tab control properties.vi" that shows how to do that.
If using Labview 6 , this link has an example, too.

Hope it helps you.

I’d like an example or description of this:
For Tab Control, change the name of the Tab Page at Runtime?
Thanks,ChrisYou CAN do this. For each tab, right-click and choose Advanced->Make Page Caption Match Label to uncheck the option.
Then, in your program, get the Pages property. Use that reference to access the Caption property.
Note that the enum strings do not change, so if the LABEL for the tab is Page 1 and the caption is hello world, the tab value is still Page 1.

Pass data between Tab Control Pages
I’d like to initiate a serial VISA session in the first page of a Tab Control to use the VISA Serial Configure.VI outputs (Visa resource name and Error cluster) in other pages or outside the tab control.
So, how can I pass those references outside the page? I used local variables, but it doesn't seem the best way to do this because I need to create several variables to capture the reference in each page of the tab control...
I created a sub-VI to initialize the VISA session, but in this case it always starts a new session every time I use the sub-VI….
Thanks in advance!

TabControl - Page1.jpg 94 KB
TabControl - Page2-3.jpg 165 KBThere's no reason at all to wire the tab control to a case statement. Since you have the read and write Booleans and they can't be clicked until the user changes tab pages, no code for the tab is necessary.With the Booleans for write and read, you should just have an event structure for those. You could initialize the serial port outside the main while loop and just pass the resource name in. Of course, if you wanted a tab for the init funciton, you could do that to but put a Boolean on that page to execute it. The only time you need to wire the tab control to a case statement is if you want to run some code immediately when the page is clicked.

This there a way to progamically duplicate a page of a tab control.
No, that would require duplicating not just the page but also duplicating all the controls and indicators on that page--which LV can't do at runtime.
No problem though, there's always a way to get where you're wanting to go. What exactly is it that you need to do?

Programmatically change tab page label font size
Hellow Fellow LabVIEW Lovers,
I thought this subject was easy with LV2009, somehow I cannot find the property for the "tab page label font size", yes, i also looked with the "pages" ref array from the tab ref, also no luck. Could someone point me to the right place? I would really appreciate your help. Thanks.
BryanOdd,
The each tab is a page Class Generic>Page.
This snippet shows that there are no objects on the page (like the lable)
However ,Page Propertise do not include lable.font.all elements

hasPlayer = false
playerversion = 10
Do While playerversion > 0
On Error Resume Next
hasPlayer = (IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash." & playerversion)))
If hasPlayer = true Then Exit Do
playerversion = playerversion - 1
Loop
is_FlashVersion = playerversion
is_Flash = hasPlayer

I have a Tab Control with approx. 15 tabs. After the user changes anything (adding text, changing a ring control, etc. ) from the default configuration on any of the 15 tabs, I would like a change to that individual tab only (say color change, text change, anything) so when the user sees all 15 tabs, they know what tab page has had changes to the defaults.
I appreciate your help with this one!
(Note: I tried using a imported bitmap control of a red checkmark - and use true/false to an
visible property node -this only works when placed in any of the Tab control pages, but not on the individual Tab itself.)
-Karl H.Karl,
I have attached a LabVIEW 6i example to this post that indicates with an LED if the control on the Tab has been changed from its default value. I used the classic LED's to make them invisible when the value is still the default. Hope this helps.

Tab control background color matching
I have a system style tab control. I realized the when the program runs in exe mode, the background color of my label on the tab control doesn't match the backgound color of the tab control. The background color of the tab control is different between exe mode and development mode. Anyone help? How do I match the color? Thanks!

Change color of portal tab strip
Hi.
In EP versión nw04s sp 16 there is a bug in the theme editor, is not posible to modify the tab color in the standard portal tabstrip.
The note 1150293 said that it should modify some css files, i do it but the tabs of standard tabstrip control do not change color...
I have clear the portal cacher, open a new browser window, restart java server...
any idea?
thanks...Thanks Aditya... but i made the modifications in this manner... i have copied the css files in other directory, edit it, and, then, i put it manually in the corresponding directory...
When, after that, i open the css files, it has the modifications than i made... but the standar tabstrip control remains with the same colors.
Any other idea?
Thank you very much and regards
