I am trying to make a GUI program in Julia using Gtk. My program includes a large number of GtkEntry boxes. However, I am running into space issues because the Entry boxes have a lot of internal padding around the actual characters. I would like to reduce, at least, the top and bottom whitespace. I have tried to use the setproperty!() function to change the height-request value, but that seems to be only able to make the box bigger, not smaller. Additionally, the margin, margin-top, etc. fields are all set to 0 by default. Again, I can make them bigger but not smaller.
Is this possible to fix? I have included below a minimal working example, a screenshot, and a Julia REPL output displaying the available properties.
Edit:
I have also tried using a css file (test.css) with the contents
entry {
margin-top: 0;
margin-bottom: 0;
padding-top: 0;
padding-bottom: 0;
}
Julia 0.6.0 code:
using Gtk
win = GtkWindow("Example")
sb = GtkGrid()
function sb_entry(label)
frame = GtkFrame(label)
entry = GtkEntry()
setproperty!(entry, :input_purpose, 2)
push!(frame, entry)
return frame
end
sb_rows = sb_entry("rows")
sb_cols = sb_entry("cols")
sb_row_off = sb_entry("row off")
sb_col_off = sb_entry("col off")
sb[1,1] = sb_rows
sb[2,1] = sb_cols
sb[1,2] = sb_row_off
sb[2,2] = sb_col_off
setproperty!(sb, :column_homogeneous, true)
setproperty!(sb, :column_spacing, 5)
setproperty!(sb, :row_spacing, 5)
push!(win, sb)
### begin edit (css)
screen = Gtk.GAccessor.screen(win)
provider = GtkCssProviderLeaf(filename="/path/to/test.css")
ccall((:gtk_style_context_add_provider_for_screen, Gtk.libgtk), Void,
(Ptr{Void}, Ptr{GObject}, Cuint),
screen, provider, 1)
### end edit (css)
showall(win)
if !isinteractive()
c = Condition()
signal_connect(win, :destroy) do widget
notify(c)
end
wait(c)
end

I know, there are at least 3 dozen questions like this on stackoverflow and still, I could not make this happen:
A simple table where thead is sticked/fixed at the top, and the tbody is scrolled.
I tried so much in the past days and now I ended up here crying for help.
A solution should work in IE8+ and newest FF, Chrome & Safari.
The difference to other "possible duplicates like this one is that I don't want to use two nested tables or jQuery (plain javascript is fine though).
Demo of what I want:
http://www.imaputz.com/cssStuff/bigFourVersion.html.
Problem is it doesn't work in IE, and I would be fine to use some JS.
Ok i got it:
You need to wrap the table in two DIVs:
<div class="outerDIV">
<div class="innerDIV">
<table></table>
</div>
</div>
The CSS for the DIVs is this:
.outerDIV {
position: relative;
padding-top: 20px; //height of your thead
}
.innerDIV {
overflow-y: auto;
height: 200px; //the actual scrolling container
}
The reason is, that you basically make the inner DIV scrollable, and pull the THEAD out of it by sticking it to the outer DIV.
Now stick the thead to the outerDIV by giving it
table thead {
display: block;
position: absolute;
top: 0;
left: 0;
}
The tbody needs to have display: block as well.
Now you'll notice that the scrolling works, but the widths are completely messep up. That's were Javascript comes in.
You can choose on your own how you want to assign it. I for myself gave the TH's in the table fixed widths and built a simple script which takes the width and assigns them to the first TD-row in the tbody.
Something like this should work:
function scrollingTableSetThWidth(tableId)
{
var table = document.getElementById(tableId);
ths = table.getElementsByTagName('th');
tds = table.getElementsByTagName('td');
if(ths.length > 0) {
for(i=0; i < ths.length; i++) {
tds[i].style.width = getCurrentComputedStyle(ths[i], 'width');
}
}
}
function getCurrentComputedStyle(element, attribute)
{
var attributeValue;
if (window.getComputedStyle)
{ // class A browsers
var styledeclaration = document.defaultView.getComputedStyle(element, null);
attributeValue = styledeclaration.getPropertyValue(attribute);
} else if (element.currentStyle) { // IE
attributeValue = element.currentStyle[vclToCamelCases(attribute)];
}
return attributeValue;
}
With jQuery of course this would be a lot easier but for now i was not allowed to use a third party library for this project.
Maybe we should change a method to archieve this goal.Such as:
<div><ul><li>1</li><li>2</li></ul></div> //make it fixed
<table>
<thead>
<tr><th>1</th><th>2</th></tr>
</thead>
<tfoot></tfoot>
<tbody></tbody>
</table>
Of course, this is not good to sematic.But it is the simplest way without js or jq.
Don't you think so?

I have been trying to figure this out. I have a fixed footer on ios with 4 links in it. Their are also 6 links under it that should not be clickable since they are below. However on ios when unless you scroll the page first the links on the fixed footer do not work and it instead clicks the link below it. After you scroll the slightest bit it works fine. I hope i explained this clearly enough.
You can see an example of it here:
amstar.m77950.com
(view on iphone)
I tried applying z-index to basically every element on the page to see if there was a fix. I also used jquery to make sure that the z-index was being applied onLoad (although it should have been anyway).
Yet i still cannot get the links in the footer to work until after you scroll the page.
Any help on this is much apprceiated. Thanks.
Here is the css i am applying to the element:
.alertsBarClass {
background: url("dynamicimage.aspx?id=21844") no-repeat scroll 0 0 #EA7E25;
border-bottom: medium none;
bottom: 0;
display: block;
position: fixed;
width: 100%;
z-index: 1000;
}
There are known issues with Position:Fixed in iOS 5.1 and anchors/links and scrolling. See the following bug #10301184, #10810232.
One thing that can help...sometimes... is to put cursor:pointer in the divs surrounding your links.
Had the same issue. Fixed it by scrolling up and down on orientation change using javascript.
I added the following script to each page, its ugly but it works:
<script type=\"application/x-javascript\">
addEventListener('load', function() { setTimeout(orientationChange, 0);}, false);
var currentWidth = 0;
function orientationChange()
{
if (window.innerWidth != currentWidth)
{
currentWidth = window.innerWidth;
var orient = (currentWidth == 320) ? \"profile\" : \"landscape\";
window.scrollTo(0, 0);
setTimeout(function() {window.scrollTo(0, 1); }, 250);
document.body.setAttribute('orient', orient);
}
}
setInterval(orientationChange, 400);
</script>
I'm having problems with IE9 ignoring the select borders when printing a multiple select.
Here's how to recreate the problem:
Open IE9 on Windows 7.
Go to w3schools's multiple select edit page.
Now highlight the options and copy/paste until there is a long list of duplicates.
Then remove the size attribute.
Click on "Edit and Click Me" so that the page reloads and you now have your modified select in the second panel.
Now, print the document (even using the XPS viewer).
For me, all of the options are printed on the page, even though the select is only 4 option elements tall. This still happens to some degree if you leave the "size" attribute at the default value of 2, but it's far more obvious when it is changed or removed.
Is anyone else experiencing this? Is this an IE bug? Does anyone know of a workaround?
You can work around this by viewing the site in IE9's compatibility mode. Usually IE will determine that it cannot display a site properly and give you the option to turn on compatibility mode from within the address bar but sometimes you need to explicitly set it.
How to turn on compatibility mode - http://www.sevenforums.com/tutorials/1196-internet-explorer-compatibility-view-turn-off.html - I used the first one in method 2.
There doesn't seem to be any CSS solution for this. Instead, I wrote a small jQuery script that copies the <select multiple> contents into a <div>, so that it can be printed. Then I applied some CSS to make it look like a select, and only show the copy when actually printing.
Script:
//jQuery required
$(function() {
if(!$.browser.msie) return false;
$('select[multiple]').each(function() {
$lPrintableDiv = $('<div data-for="' + this.id + '" />').addClass($(this).attr('class')).addClass('printable');
//update printable on changes
$(this).after($lPrintableDiv).change(function($aEvent){
updatePrintable($aEvent.target);
});
//run once on load
updatePrintable(this);
});
});
function updatePrintable($aTarget) {
var $lSelect = $($aTarget);
var $lSelected = $($aTarget).val();
var $lPrintable = $('[data-for="'+$aTarget.id+'"]');
$($lPrintable).width($lSelect.width()).height($lSelect.height());
$($lPrintable).html('');
$($aTarget).children().each(function($lElm){
$lVal = $(this).val();
$lLabel = $('<label />').text($lVal);
$lOption = $('<input type="checkbox" />').val($lVal);
if($(this).is(':selected'))
$lOption.prop('checked', true);
$lPrintable.append($lOption).append($lLabel);
});
}
CSS:
.printable {
border: 1px solid grey;
display: none;
overflow: auto;
}
.printable label {
display: block;
font: .8em sans-serif;
overflow: hidden;
white-space: nowrap;
}
.printable [type="checkbox"] {
display: none;
}
.printable [type="checkbox"]:checked + label {
background: #3399ff;
color: white;
}
#media print {
select[multiple] { display: none; }
.printable { display: inline-block; }
.printable [type="checkbox"]:checked + label { background: grey; }
}

I'm using zfdatagrid to display a table within a Zend app. How do i fix the width of the table? I can't find any setting in the grid.ini.
public function displaytemptableAction()
{
$config = new Zend_Config_Ini(APPLICATION_PATH.'/grids/grid.ini', 'production');
$db = Zend_Registry::get("db");
$grid = Bvb_Grid::factory('Table',$config,$id='');
$grid->setSource(new Bvb_Grid_Source_Zend_Table(new Model_DbTable_TmpTeamRaceResult()));
//CRUD Configuration
$form = new Bvb_Grid_Form();
$form->setAdd(false)->setEdit(true)->setDelete(true);
$grid->setForm($form);
$grid->setPagination(0);
$grid->setExport(array('xml','pdf'));
$this->view->grid = $grid->deploy();
}
It seems the table width is controlled via a css file in folder './public/styles'
td div input[type='text'] {
width: 98% !important;
border: 1px solid #ddd;
}
Another nice API with rubbish documentation.
Just style it inside your css file like you would any other element. You can right-click view source on the page generated and see what kind of classes(if any) are given to the table/tr/td`s.
