Make ATTR_TITLE_FONT for GetPanelAttribute() work for top-level panels.

Status: New Submitted by Active Participant on 12-21-2012 08:12 AM Comment

It would be convienent if I could use ATTR_TITLE_FONT attribute with GetPanelAttribute() on top-level panels to obtain the Windows font properties for the title bar (this would be the font that the user can customize in the "Display Properties" in Windows Control Panel).  Currently this attribute only works for retrieving the font for child panels.  Thanks.

Advanced UIR design or control behavior

Status: New Submitted by Member on 11-22-2012 05:29 AM Comment

Hi community

 

To have more flexibility on the UIR conception, it would be convenient that controls or panel have a structure and behavior similar to Java Object (Java swing tutorial).

 

It would be necessary that CVI offers a list of basic control as it is the way today. But it would be interesting that CVI offers some special controls which could be a composition of multiple basic controls (or simply a composition of panel with its control). (Refers to Java containers)

 

IE: I create a panel composed with a picture control, a text control and a button control. Then I would like to have a control which able to react like a list control but each item of this list would be my composed panel.

 

IE: I create a preformatted “top panel” with some control to search, apply … then into this panel I have an area able to contain another panel. With this, I’m in position to change the panel into the area and preserving the design of the “top panel”.

 

IE: I could insert into a combo box an object like a radio button or a button instead of an numerical ou string item as it the way today.

 

I don’t know if this suggestion is understandable?

Combobox improvements

Status: New Submitted by Active Participant on 11-19-2012 09:49 AM 1 Comment

I like the Combo Box controls which are available in CVI, and I think there is some room for some improvements.

 

1.  Make their appearance more similar to the available Ring controls.  Right now the Combo Box has a look unlike the other available controls which can make a UIR that mixes Combo Boxes with Rings and Lists rather jarring.

2.  A numeric Combo Box control.

 

Thanks.

Improved MultiFileSelectPopupEx and DirSelectPopupEx functions allowing to select files from more than one directory

Status: New Submitted by Trusted Enthusiast on 09-30-2012 05:29 AM Comment

Starting with CVI2012 NI provides Win7 style popup menus to select files or a directory. Unfortunately, with the new functions is is not possible to select files from more than one directory, and it is also not possibly to select multiple directories. So one has to choose either to use the old-fashioned, outdated look and feel from the MultiFileSelectPopup function, or to use the new design but limited functionality... This choice is not a good one

 

I vote for a combination of the two - the look of the new and the features of the old functions

adjust MultiFileSelectPopupEx to FileSelectPopupEx

Status: New Submitted by Trusted Enthusiast on 09-16-2012 04:26 AM 1 Comment

Hello,

 

the FileSelectPopup(Ex) provides the option to choose 'Select' or 'Load'... buttons with the benefit that the users choice of files can be limited to existing files only.

 

Unfortunately, the new MultiFileSelectPopupEx behaves differently, with the new function the user can always select new file even if it doesn't make sense in a specific context, hence the programmer has to take extra care for this scenario. Also, the response is different for "newfile.c" "existing1.c" "existing2.c" and "existing1.c" "existing2.c" "newfile.c". From a users perpective, however, this doesn't make much sense.

 

I understand that most of these restrictions result from Windows and thus can not be easily changed.

 

But may be it is possible to use a similar idea of different buttons (OK vs. Select) for the multifile popup, too, allowing the programmer to limit the user to select exisiting files only. OK would keep the current behavior, while Select would restrict the choice of files to existing files only.

 

Thanks!

Problem with error windows hidden underneath user panels

Status: New Submitted by Active Participant on 05-16-2012 09:11 AM Comment

One problem that I've had, while debugging a rather large program with a complex user interface and lots of panels, is that quite often, if (when) the program crashes (say, due to an operation on a NULL pointer) the pop-up that displays the error is hidden beneath the currently open program panel which, of course, cannot be moved or otherwise touched because the program is halted. Likewise, I often find myself moving the LabWindows panel around on the screen while in debugging mode,  trying to see the currently executing line which is hidden behind some GUI panel.

 

It would be most helpful if all error pop-ups (indeed the entire LabWindows/CVI interface) had the highest priority and display on top of anything else on the screen.

Follow Eclipse's lead: while-typing code analysis (e.g. for struct member display); refactoring,

Status: Under Consideration Submitted by Active Participant on 05-16-2012 08:59 AM 4 Comment

One of the more valuable tools within LabWindows is the ability of the editor to fill in struct elements given the struct name. I also work with Eclipse-based tools for embedded systems work, and it has a similar ability. Unfortunately, whereas Eclipse dynamically analyzes the code as it is written, and can provide stuct elements (and other variable information) as soon as the programmer types it in, LabWindows cannot provide this information until after the code has been successfully compiled. As this may or may not happen for some time after the file has been started, or major changes begun, it is almost useless.

 

Another useful tool that Eclipse offers that LabWindows does not is the ability to refactor variables and other symbols. Again, Eclipse dynamically tracks the code as it is written, not requiring compilation; refactoring is similar to global replace, except that it tracks the 'C' usage of the symbol and only changes the proper usage. So, for instance, if I use a local variable named "X1" in three different subroutines, and refactor "X1" to "X2" in one of them, only the variable in the particular routine gets changed.It works with any C symbol, including routine names, global and static variables, and structures.

 

As a matter of fact, I would encourage NI to look into the possiblity of basing LabWindows on the Eclipse platform, as Atmel did in replacing its proprietary Studio software with an Eclipsed-based version. This would enable users to take advantage of a large number of available Eclipse tools, such as source-code management.

debug_printf

Status: New Submitted by Active Participant on 05-16-2012 09:19 AM 1 Comment

Might it be possible to implement some utility so that the debug_printf function could print to a window (or even the debug-output window in LabWindows/CVI) from a program that is NOT running under the debugger? I'm workng on a program that does some near-real-time data acquisition, and running it with the debugger from within LabWindows/CVI slows it down too much, to the point where it can't respond to the DAQmx notifications and the program crashes. Since I have a multi-core machine, I can, however, run it as a separate process at the same time as LabWindows/CVI.

call tree analysis

Status: New Submitted by Active Participant on 05-16-2012 09:00 AM Comment

* It would be nice to have a tool that automatically generated and maintained .fp files for subroutine libraries. Keeping these up to date is a pain.

 

* It would be most helpful to have a subroutine call-tree analyzer tool built into LabWindows. I'm working with a rather elaborate user interface at the moment, and I am totally losing track of what routine calls what. It's especially difficult because I use the "CallCtrlCallback" function quite a bit, especially during initialization, and I'm very afraid of accidentally implementing a recursive loop without realizing it. such a tool would, of course, have to be able to follow through the callback functions of controls, and perhaps into NI libraries that use callbacks.

Better treatment of linear -> logarithmic scaling of graph axes

Status: Duplicate Submitted by Trusted Enthusiast on 05-03-2012 02:37 PM 4 Comment

Hello,

 

as discussed in this thread changing the map mode of a graph axis from linear to logarithmic scaling may perform sub-optimal if the graph shows plots containing zero or negative data values. Fortunately, there is a workaround.

 

The suggestion presented here is to make this workaround unnecessary... Ideally, the graph should take care by itself if plots need to be updated, i.e. changing the attributes ATTR_XMAP_MODE and ATTR_YMAP_MODE from VAL_LINEAR to VAL_LOG should result in updated plots.

File Select Popup to have 'Save As Type' option

Status: New Submitted by Member on 04-29-2012 11:25 PM Comment

A number of CVI applications I have written would benifit having the 'Save as type' option on the FileSelectPopup dialog (when the button label is save).

 

There are many simple workarounds, but these all result in a clunky and not so clean GUI.

 

It is fairly commonplace these days for an app to save a file in more than one format/filetype. For example, the dialog for saving a .uir file in the CVI IDE gives the option to save as an earlier version.

Multiple Clipboards

Status: New Submitted by Active Participant on 03-12-2012 11:26 AM 1 Comment

Summary:

Implement and add easy access to multiple clipboards inside the CVI ADE.

 

Description:

The CVI ADE (at least the source editor) should keep the most recent sequences of text that had been copied (Ctrl+C) to the clipboard.

It should also allow access to the multiple clipboards through some pop-up menu, displayed at a certain keystroke combination.

Tree: ATTR_VISIBLE for SetTreeItemAttribute ()

Status: New Submitted by Member on 03-12-2012 05:52 AM Comment

Same as the post "ATTR_DIMMED". I want to hide some tree items without deleting them. My work around is currently, to set the item size of the item, which shall be not visible, to 1 (0 is not supported). The disadvantage is, that the "small" items are still shown and there are big spaces between the "visible" tree items.

Copying Tree Items

Status: New Submitted by Member on 03-12-2012 05:43 AM 5 Comment

When I use the function "CopyTreeItem", the item is copied, but the value (behind the item is automatically increased or changed). Because the item might be used several times and the item is identified by its value, it is necessary, that the value behind the item is NOT changed. Please don't change the value of the item, when it is copied or please add a parameter, which handles the changing of the value (e.g VAL_DONT_CHANGE, VAL_LAST etc.).

Adding options to context menu on menu items in the UIR editor

Status: Duplicate Submitted by Proven Zealot on 03-07-2012 02:32 AM 1 Comment

Presently there is a context menu for menu elements to generate / jump to a menu item callback. These items are not present in top level menus that have a callback function installed (those with the exclamation mark appended), where only 'Edit' item is present. It would be handy to have these options added to those items too.

Make "Conform to System Colors" the default for new panels in the UIR editor.

Status: Already Implemented Submitted by Active Participant on 02-15-2012 12:09 PM 3 Comment

It would be convienent if this was the default, especially since the behavior now is to take the panel color from however Windows is set up on the development machine.  I find this both odd and inconvienent as it makes this error hard to catch as the panels look okay on the development PC.  Thanks.

Add a numeric control ATTR_SET_RADIX

Status: Duplicate Submitted by Member on 01-25-2012 01:26 PM 2 Comment

When a user changes a numeric control radix, LabWindows/CVI generates an EVENT_RADIX_CHANGE event and sends the event to the control callback function.

eventData1 = The new format of the radix(VAL_DECIMAL_FORMAT, VAL_HEX_FORMAT, VAL_OCTAL_FORMAT, or VAL_BINARY_FORMAT).  Provide an attribute to set the radix from source code.

Check for duplicate keyboard accelerators in controls

Status: Under Consideration Submitted by Member on 01-17-2012 08:55 AM 1 Comment

I find it desirable to have the UI engine run, in debug mode and only optionally in release mode, a duplicate check on keyboard accelerators on controls (like labels or command buttons, as in __Quit being rendered as Quit and enabling the user to press [Alt]+[Q]). All too often, on bigger panels, when adding a feature, I find that a shortcut/accelerator is already assigned.

 

Note that the UI editor per se isn't sufficient while controls can be added programmatically.

Add an interface to allow for items to be added to the application "window menu".

Status: New Submitted by Active Participant on 12-14-2011 11:34 AM Comment

It would be convienent at times to be able to insert items that would appear alongside the default Restore/Move/Size/Minimize/Maximize/Close items in the "window menu" that pops up when the icon in the top left of the application is clicked (or the alt-space key), such as seen with Windows' own Command Prompt program (see screenshot).  Thanks.
