I'm trying to make Eclipse UI more compact and already have successfully tweaked it using these instructions:
Can I make Eclipse on Ubuntu look more compact?
https://gist.github.com/andrioli/3825078
The only remaining thing I want to improve is reducing vertical spacing between menu items as on this picture:
.
I looked through GtkMenuItem style properties, but can't find any setting for that. GtkMenu::vertical-padding also doesn't seem to be right one.
Is there any Gtk2 widget property that I can modify to do it?
There are a couple of settings in your theme's gtkrc file that you can modify to make the menu items more compact:
To reduce the width and height of the menu items, you can assign a smaller value to the xthickness and ythickness properties respectively (horizontal and vertical padding respectively between the text and border of a widget). e.g.
style "menu_item" {
xthickness = 1
ythickness = 1
}
The above code snippet assumes your GtkMenuItem widget uses a style called menu_item in your theme's gtkrc file. i.e.
widget_class "*<GtkMenuItem>*" style "menu_item"
The height of the separator menu item (line separating menu items) can be reduced by assigning a smaller value to the GtkWidget::separator-height property. e.g.
style "separator_menu_item" {
xthickness = 1
ythickness = 1
GtkSeparatorMenuItem::horizontal-padding = 0
GtkWidget::wide-separators = 1
GtkWidget::separator-width = 1
GtkWidget::separator-height = 1
}
Again, the above code snippet assumes your GtkSeparatorMenuItem widget uses a style called separator_menu_item in your theme's gtkrc file. i.e.
widget_class "*<GtkSeparatorMenuItem>*" style "separator_menu_item"

I'm trying to use .NET Core GTK. For WinForms, we can select the form, and then click the Font property to change the font face or size within the Form designer. If we change the top form's font, it is applied to all the child controls on the form.
I wanted to do similar thing in Glade, but I cannot find a "Font" GUI in any of the attribute tabs.
Is this possible with GTK#?
If so, can it be done within Glade?
If the answer to 2 is no, can it be done in the code?
Yes this is possible in both GTK and Glade, although some code will be required to change all the forms font.
In GTK you will be using the GtkFontChooserWidget. This should let you choose between fonts.
In Glade, when you are using the attributes tab you are able to change font size with the Scale attribute. I haven't yet figured out how to change the actual font through those attributes yet. Thankfully there is a workaround. Instead of using Attributes, use Markup. Markup works just fine for both font size and font style.
Markup Example
<span font='36' face='Georgia'>Markup</span>
Assuming you are using a GtkComboBoxText to list possible fonts and button for selecting, you would just need a handler that would go through each of the labels and change the font to the designated one.
def when_visible(window):
"""
This is where per-window initialization takes place.
Values to be displayed are populated into their widgets.
"""
global FONT_FACE
name = Gtk.Buildable.get_name(window) # Window currently on
if 'font_select_screen' = name:
font = BUILDER.get_object('fontEntryCombo')
FONT_FACE = font.get_active_text()
elif 'random_screen' = name:
label1_text = "<span font='36' face='{}'>Label</span>".format(FONT_FACE)
label1 = BUILDER.get_object('label1')
label1.set_markup(label1_text)
I'm using custom cursors and it need to be differ in some components in my screen.
When I set the cursor for Accordion, it doesn't effects title headers but effects the body of each TitledPanes. I even tried to set the cursor for each TitledPane but it doesn't effect the title header. I'm using following way to change the cursor.
ImageCursor cursor_title = new ImageCursor(cursorImg_title,cursorImg_title.getWidth() / 2,cursorImg_title.getHeight() / 2);
accordionBody.setCursor(cursor_title);
Is there a way to change the cursor in title bar of a JavaFX Accordian?
More....
I have changed the padding of title bars using css as follows. Hope it doesn't have any relation to the problem.
.titled-pane > .title {
-fx-padding: 30;
}
A TitledPane is divided into two parts :
Title
Content
When you are setting the Cursor on the Accordion, it delegates it to the content of each TitledPane, but leaves the Title. This is by design.
To force your application to change the cursor on the title as well, we need to set it on each of these nodes. We can fetch all the nodes by using the lookupAll() on the accordion and passing the styleclass they use i.e. .title. Make sure you use this after the scene graph is visible.
accordion.lookupAll(".title").forEach(node -> node.setCursor(Cursor.CLOSED_HAND));
You can use your custom cursor in place of CLOSED_HAND.
I would like to rip off Google's design for my Continuous Form. The detail section of the form is set up to display N number of records resulting from a search, and thus cannot be used to create this effect (i think). Everything must go in the header section.
there are 2 primary issues I would like to address in this question:
Two toned background. The header section should have a grey stripe and a white stripe. This stripe needs to extend the full width of the form, which is variable and will depend on the user. (i'm using tabs not pop-ups)
How to right justify certain elements of the header so that they stay close to the right edge, wherever that may fall, just like your account information on Google.
The "Search Results" in the detail section are loaded by setting the form's recordSource to the results of a query defined in VBA, which takes parameters from the search box. The form is continuous.
Any ideas how to hack this into place?
Recent versions of MS Access provide improved form layout features when using the ACCDB database file format.
The screen captures below are based on a form in Access 2010. The second image is after the form width was expanded, but it's scaled down for display on this web page. However you can open those images directly to compare their relative widths.
The grey color is from the form header's Back Color property. The white box is a simple text box whose Back Color is white and Back Style is Normal (not Transparent).
The text box's Horizontal Anchor property is Both, and its Can Grow property is Yes. The other 3 items ("?", "Button 2", and "Button 3") are command buttons. Their Horizontal Anchors are set to Right and their Can Grow properties are No.
The result of those properties is that when the form expands, those command buttons maintain their size are are kept right-aligned within the form. And the text box stretches to fill the remaining available space.
Note this behavior is accomplished without any VBA code.
I think these layout capabilities were introduced in Access 2007 and perhaps refined in 2010.
For the background, use two rectangles with transparent borders, one back color gray, one white. You can size them to the form by using the form's InsideWidth property. For example:
Private Sub Form_Resize()
rect1.Width = Me.InsideWidth
rect2.Width = Me.InsideWidth
End Sub
I would do a similar thing for the buttons/images/etc you want right justified. Set their Left property relative to the form's width:
mySettingsButton.Left = Me.InsideWidth - 300
Keep in mind all the measurements are twips (1440 twips/inch)
How do you center text line-by-line in a UIButton using Interface Builder? I am scouring the options and just don't see it. Here's the button:
You can't set the text to be centered in your nib. But you can change the alignment in your code:
- (void)viewDidLoad {
[super viewDidLoad];
self.myButton.titleLabel.textAlignment = UITextAlignmentCenter;
}
I know this is an old question, but I came across it in my own attempt to center the multi-line text of a UIButton in IB. What I found is that by default, when "title" is set to "plain" and "line break" is set to "word wrap" the longest line of the title text is centered and the other lines are left justified to this line (similar to the OP's screen capture).
In order to have all the lines centered properly, "title" needs to be changed to "attributed." This provides many more options to customize the appearance of the title text. Center each of the lines of text (you can now actually change the alignment for each line individually). Also be sure to set "line breaking" to "word wrap" under "more..." above the text. There seems to be a bug with how this line breaking option behaves, at least in Xcode 4.5 at this time, because the text on the button in IB will look incorrect, truncating everything except the first line. It seems the "word wrap" and truncate options are interpreted backwards in IB, but if you run the app it behaves correctly in the simulator.
Actually you can do it in interface builder.
Just set Title to "Attributed" and then choose center alignment.
#from comments : To wrap you need to set Line Break to Character Wrap or Word Wrap.
P.S : This might not render in xcode. But, it will work at runtime.
You can set the center multiline text in UIButton through storyboard.
This is how you make the text have two or more lines.
Set the below key Path at
Identity Inspector --> User defined runtime attributes --> add new key value pair with below
titleLabel.textAlignment - NSNumber - 1
and
titleLabel.numberOfLines - NSNumber - 5 - or use "0" meaning "any number"
It will look like this:
Note that (2016) unfortunately it does not actually show the two or more lines of text in Storyboard (you see only the first one), but it works perfectly when you run in simulator or device.
For IB set Title to "Attributed" and select center alignment (like Alexander Danilov suggested)
But if you want to do it in code using Swift 4:
// center button text
yourButton.titleLabel?.textAlignment = .center
// enable multiline if needed
yourButton.titleLabel?.numberOfLines = 0
Not all options are done using Interface Builder therefore you must do some of them by coding, and usually we do them inside the function viewDidLoad.
To center your text inside a button by code you can use the following:
button1.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
You can use the same technique to align the text to any direction, for example to the left:
button1.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
But this will take the text too much to the left and you might want to have some space before it keeping the alignment to the left, so you add an inset after the aligning code as follows:
button1.contentEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
In this case we are pushing the text from the Y axis by 10 points. I say here points not pixels because as you know Apple uses the points technique to measure distances to be able to adapt easily between normal display and retina display (where retina is 2 times the normal one).
I haven't tried it out yet, but I think a way to do it might be create a CGRect on top of your button, then use it as a frame, create a label, and then you can play with the label, set the textAlignment property to be UITextAlignmentCenter, and set the background color to be clear.
This works with uitableview but I don't know whether that will work for button. Hope this helps.
I am trying to change the colour theme of an old VB6 application (make it look a bit more modern!).
Can someone tell me how I could change the backcolor of every control on a form without doing it for each and every control (label, button, frame etc!).
I have about 50 forms, all containing such controls and doing this manually for each form in code would take an age!
I am also open to better suggestions and ideas on how I can skin / theme a VB6 application?
Thanks in advance
The .frm files are simply standard ANSI text files. A background color property of a control would look like this:-
BackColor = &H80000005&
(Note the above is a system color but you can specify the RGB color using by using the lower 3 bytes and leaving the high byte 0).
A control such a Label would look like this:-
Begin VB.Label Label1
Caption = "Hello:"
Height = 285
Left = 90
TabIndex = 3
Top = 480
Width = 1305
End
So that task could be done lexically by parsing the .frm files and inserting (or replacing) the BackColor attribute line.
Edit:
Useful link posted in comments by MarkJ : Form Description Properties
You can do a for each and eliminate the controls you don't want.
Dim frmThing as Form
Dim ctlThing as Control
For Each frmThing In Forms
frmThing.BackColor = vbYellow
For Each ctlThing In frmThing.Controls
If (TypeOf ctlThing Is TextBox) Or _
(TypeOf ctlThing Is CheckBox) Or _
(TypeOf ctlThing Is ComboBox) Then
ctlThing.BackColor = vbYellow
End If
Next
Next
you could do this at runtime by looping the Controls collection and setting the background of each. This would give you the flexibility of changing your theme.
You could also work through the source files, parse out the controls and enter/change the background colours that you want. This approach is probably more work, for less reward.
Just for completeness...
ssCheck does not have a BackColor property and will produce an error using the aforementioned methods

It's going back quite a few years now, but wasnt there a 'Transparent' background color?
Set all the labels to have a transparent background, and you only need to set the form color once.
