How to define the size of each column of a GridLayout in HTMLB?

Hi there,
I think everything is in the subject. It seems it is not possible. The GridLayout.setWidth() refers to the grid in general and it is not possible to select a GridLayout column (in order to apply to it a setWidth()).
When I do a GridLayoutCell.setWidth() I can't see any change as well.
Maybe the only possibility is to nest several GridLayout?
Does someone have a clue on this?
Thanks in advance
Renaud

Here is my code:
GridLayout gl = new GridLayout();
gl.setCellSpacing(10);
gl.setWidth("50%");
Here it's inside a loop:
GridLayoutCell imageCell = new GridLayoutCell(sapLogo);          
imageCell.setWidth("20%");
gl.addCell(++cellrow, 1, imageCell);
GridLayoutCell linkCell = new GridLayoutCell(link);
linkCell.setWidth("40%");
gl.addCell(cellrow, 2, linkCell);
GridLayoutCell radioButtonCell = new GridLayoutCell(radioButtonGroupGUI);
radioButtonCell.setWidth("40%");
gl.addCell(cellrow, 3, radioButtonCell);
I tried to change the percentage values but it never works how I want. I need the first column to be very thin.

    Use Set Waveform Attribute on each channel of your data.  Set an attribute with name "NI_ChannelName".  The value is a string containing the name you wish to call the channel.

  • How to define the size of report area and its elements?

    How can I define the report area size and its elements? And how can I define that for each printed paper, the details area will repeat horizontally or vertically?
    Is there any way to change the measuring units?
    Are there any difference between Crystal Reports that is bundled with Visual Studio 2005 to the standalone version that don't allow me doing what I need?
    Thanks.

    Hi Juliano,
    I hope this is what you had in mind...
    1.  File / Page setup: set your paper size, portrait/landscape and margins.
    2.  Section Expert: the page header &footer sections are 'locked' in that each page will have the space indicated dedicated to these sections; report header & footer - this is the space dedicated on the first and last page of the document. The remaining space available will be used up by the Details section.
    I'm not sure how you can get the Details to print verticall vs horizontally - except maybe with cross-tab format.
    3.  Measuring units: is this for the ruler? This is pulled from your computer settings.
    The rest I'm not sure about but I hope this is enough to get you started!

  • How to change the Size of a Column in TimesTen

    I have a Column of type VARSHAR2(32). I would like to increase the size to 255;
    Is the only to do this is to drop the table and add it again?

    Dropping and re-creating the table is by far the best way (of course you need to unload the table's data to a flat file with ttBulkCp first and then reload it again afterwards).
    a second option is to drop the column and re-add it with the new size but you still need to preserve the data first and put it back afterwards and this is harder for a single column than for a whole table. Also, if you are using replication you should exercise care when using ALTER TABLE to ensure iall replicated copies of the table maintain the same physical structure.

  • How to define the size of a EVS as 0(null)

    Hi,
    Actually in my project I have done 3 fields
    1.firstdate
    2.Lastdate
    3.Absence Type(EVS which hold the data from BAPI)..
    When I select firstdate and lastdate it is calculating and it is showing the no of days by clicking of a action..and when selction of some conditoin(like some sickleave it should show medical check box otherwise not)...
    Everything is working fine..
    1.selcting of date (FD and LD)and selecting of that EVS(Sickleave)it is coming the output..
    2.selcting of date (FD and LD)and selecting of that EVS(other kind of leave )it is coming the output
    but my problem is that without selcting the EVS field when i select(FD and LS)it is showing null pointer Exception..here I have to select the EVS Feild..but it should not be like this....all are indepent ..so here I have to check the size of a EVS Field. as null...but it is not supporting in NWDS..Is there other way..
    public void onActionfullday(I created one action)(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
        //@@begin onActionfullday(ServerEvent)
    wdThis.wdGetCustContLeaveReqController().Bapi1(wdContext.currentContextElement().getAbsent_From(),wdContext.currentContextElement().getAbsent_To(),"CH","CH");
              if(wdContext.nodeBapi_Working_Days().size()>0 ){               
              wdContext.nodeBapi_Working_Days().moveFirst();
                   wdContext.currentContextElement().setAbsdays(wdContext.currentBapi_Working_DaysElement().getWorking_Days());
    if(wdContext.currentContextElement().getAbs_Type().equals("Accident")||wdContext.currentContextElement().getAbs_Type().equals("Accident 25 %")||wdContext.currentContextElement().getAbs_Type().equals("Accident 50 %")||wdContext.currentContextElement().getAbs_Type().equals("Sickness 25 %")||wdContext.currentContextElement().getAbs_Type().equals("Sickness 50 %"))
              wdContext.currentContextElement().setMedical_visible(WDVisibility.VISIBLE);
         else
                        wdContext.currentContextElement().setMedical_visible(WDVisibility.NONE);
    without selecting absence type and selecting of the FD and LD i should get the result boz these two fields are not dependent of each other.......

    Hi Suman,
                  if your problem is to avoid null pointer exception for EVS, before executing  RFC you can check (wdContext.node<EVS>.current<EVS>element!=null). then you can populate a message for warning the user to enter EVS field.
    and stop executing RFC.
    thanks

    netdownwidget.width = 100
    in awesome-git the syntax is different.  i would recommend using the non-git-version, because the most tutorials are for older versions.
    without reading the references of the git version,  try something like netdownwidget:set_width(x)
    // edit: your icons arnt centered, maybe ur interested in that command:
    for x in *.xbm; do convert -fill "#afa72e" -transparent white -colorize 100 -bordercolor transparent -border 8x8 -gravity center -crop 16x16+0+0 "${x}" "${x%.*}.png"; done

  • How to define the size of saving image in sm or inch?

    Hi,
    is it possible to get the image of size defined in sm or inch?
    There is no stable proportion between width in pixel and sm.
    My purpose is to create a buffered image of defined size ( for example 5x5 sm) and save it. The saving is made with encoder in jpeg.
    Thanks and Regards,

  • How to let the user define the colors for each plots in the graph (I use LabVIEW 7)?

    How to let the user define the colors for each plots in the graph (I
    use LabVIEW 7)?

    Hi,
    Take a look at this example, it uses property nodes to select tha
    active plot and then changes the color of that plot.
    If you want to make the number of plots dynamic you could use a for
    loop and an array of color boxes.
    I hope this helps.

  • Time Machine: How can I find the size of each individual backup?

    When I look in the Time Machine external hard drive under Backups.backupdb, I see all of the backups. I also see the total space remaining on the Time Machine. However, I would like to know the size of each individual backup file. Is there a way to get this information? It does not show in the "Get Info" window of the backup.
    Thanks

    The question is ambiguous, because a snapshot may consist almost entirely of references to other snapshots and thus take up almost no space on the backup volume. There is a shell command that enables you to see how much data was copied from the sources in the last snapshot. An example of how to use it is below.
    Triple-click anywhere in the line below to select it:
    tmutil compare
    Copy the selected text to the Clipboard (command-C).
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V).
    The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
    Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
    Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
    Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
    Files that you’ve excluded from backup, or that are excluded automatically, are ignored.
    At the end of the output, you’ll get some lines like the following:
    Added:
    Removed:
    Changed:
    These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.

  • In CS6, why the file size remains same after croping? And how do I reduce the size after each cropin

    In CS6, why the file size remains same after croping? And how do I reduce the size after each croping? Thx

    Select the Crop Tool and check the box [  ] Delete Cropped Pixels and you should see a reduction in file size.  With the box unchecked, the data is still maintained in the document, you just can't see it.
