LabWindows/CVI Idea Exchange

Hello,

 

I have 2 suggestions for graph improvements.

 

1/ I suggested the first one a long time ago but it has never been implemeted so I try again trough this idea exchange board.

I would like to have the possibility to change the grid lines style to dash or dot. Today only solid is available.

I have written a routine to do it for printing graphs but as you can see it in the attachment it is not always working properly.

 

2/ It would be nice to have the possibility to set a percentage of transparency for the plots. In the example attached you can see if the green plot would have been behind the blue some parts would not have been visible. By setting the percentage of transparency of the blue one the green if behind the blue would become partly visible.

 

These 2 features are already available in the 3D graph so it would be nice to have them also on 2D plots.

 

Regards

Hi,

 

sometimes it woud be useful to have plot symbols available that are larger than the fixed standard size. Hence I suggest providing a plot attribute ATTR_TRACE_POINT_SIZE where one could set the point size (e.g. in pixels)

support of Unicode character set would be most welcome

Somewhat similar to SetBreakOnLibraryError, I suggest the addition of a function that does a breakpoint when the specific attribute of a panel/control changes.
It could work like this:

SetBreakOnCtrlAttributeChange(panel, control, Attribute)

with also:

ClearBreakOnCtrlAttributeChange(panel, control, Attribute) // Use -1 to clear them all

SetBreakOnPanelAttributeChange(panel, Attribute),

ClearBreakOnPanelAttributeChange(panel, Attribute) // Use -1 to clear them all

 

Example of use:

SetBreakOnCtrlAttributeChange(panel, control, ATTR_CTRL_VAL)

SetBreakOnCtrlAttributeChange(panel, control, ATTR_VISIBLE)

It has been discussed a few times in the forum so it might be appropriate to also ask here for the implementation of a native polar plot, i.e. plot r versus theta, with radial grid lines and all the corresponding ingredients.

As suggested about two years ago (http://forums.ni.com/t5/LabWindows-CVI/Is-it-possible-to-have-an-explicit-sign-in-numeric-controls/m...) I am still looking for a possibility to explicitly show the positive sign of a numeric value in numeric controls, i.e. the control should display '+6.789' instead of '6.789'.

 

Phrased differently I would like to have one more attribute 'SHOW_POSITIVE_SIGN' that could be set to

 

0: don't show the plus sign, i.e. display numbers as is implemented now, default

1: show plus sign for positive numbers

2: show plus sign for positive numbers and zero

 

 

When designing a new user interface it would be very helpful to have the ability to lock a control's position within a panel.  It is far to easy to inadvertently select and move a control that you have already spent time precisely positioning within a panel.

Hi,

 

it has been discussed a few times in the forum of how to implement a check box control in a table, e.g. here. At present, this type is not natively supported. In principle, as second best possibility, one could use suitable image controls, but the 'correct' image of a check box depends on Windows version, theme, etc. Hence it would be much nicer to have a native check box control - thanks

CVI currently jumps to the first entry in the build output window, whether this is a warning or an error. I'd like to suggest an option to see the point of the first error, if there is any, before any warning. Maybe they could be color coded, too. When starting a new project I usually place some TODO messages (#pragma message) and if this is in a global header file I always see this and not the build error.

Hello,

 

searching through the C code for specific controls first and foremost requires the knowledge of the control's name... If there are some hundred it may get difficult to remember and thus I typically have to check the UI for the constant name. Clicking on the control shows its name in the status bar, a welcome feature, but unfortunately I cannot directly use this text for searching...

 

 

What I suggest is allow copying this status bar field using CTRL+C; then it's possible to switch to the C code, press CTRL+F and CTRL+V... (The property browser is not really useful here because it only lists 'NUMERIC_7' and misses the associated panel)

 

Another, even more powerful feature would be to add a right click popup menu either to this status bar field ('Search C code for this constant') or to the control popup itself: Besides 'Generate control callback' etc. I'd like to see another entry 'Find control in C code'

 

Thanks!
