I am using absolute positioning when writing text in a PDF document using iTextSharp. It can only deal with BaseFont and it is not possible to set a Bold decoration on a base font.
I read in a post that this was the way to set the font to bold:
pdfContentByte.SetCharacterSpacing(1);
pdfContentByte.SetRGBColorFill(66, 00, 00);
pdfContentByte.SetLineWidth((float)0.5);
pdfContentByte.SetTextRenderingMode(PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE);
That worked but created a another problem. I don't know how to set these parameters back to my old default (none-bolded font).
Do you know how?
TIA

the answer is very simple: you need to save the state before you change it, and restore the state after you've added the text:
pdfContentByte.SaveState();
pdfContentByte.SetCharacterSpacing(1);
pdfContentByte.SetRGBColorFill(66, 00, 00);
pdfContentByte.SetLineWidth((float)0.5);
pdfContentByte.SetTextRenderingMode(PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE);
// add the text using the changed state
pdfContentByte.RestoreState();
The changes you make to the character spacing, color, line width and rendering mode will only be valid between the SaveState() and RestoreState() sequence.

So, I have a growing string with many "\n". Every app start I will load the total string and every app use some new lines will be added.
The string is inside the Content of a ScrollView. But the Content size is not scaling with the string length. I want the Content to be exactly as high as the text lines go and be scrollable.
I can think of calculating the line count and set the content height manually. But maybe there is a more simple way? Please tell me your solutions.
I found a convenient non-code answer myself. You put the Text-Component directly on your Content GameObject. Then you use a ContentSizeFitter and set Vertical: Preferred. Also the Content anchors have to be set for variable height.
This enables me to dynamically set and scroll through a different text length with a ScrollView. (The font size is kept, to still fit the rest of the GUI)
I am still open for other answers.
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)
Some kinds of text are in an encoded form, I want to convert them all to UTF8 form.
Such as convert "%E6%B5%8B%E8%AF%95" to "测试" but also do not change the file, meaning "%E6%B5%8B%E8%AF%95" is displayed as "测试" until I edit it.
Is there a way to do that?
I tried activeEditor.setDecorations(), but it can only change the style and also cannot hide the original text. I also tried HoverProvider - it helps, but it's not exactly what I want.
This is indeed possible by using decorations (at least now in 1.52.1).
We can add text with the before or after properties.
And we can hide the original text by setting its opacity to 0 and by abusing letterSpacing with a negative value to reduce its effective width to 0.
const replacementDecoration = vscode.window.createTextEditorDecorationType({
opacity: '0',
letterSpacing: '-100px',
before: {
contentText: 'test',
}
})

GWT newbie here. I have found that when I make a TextArea read-only useful features such as dynamic expansion and even word-wrapping stops working. My intention was to move a string from one text area, append it some way to some more strings, and then add this string into my read-only TextArea. I have doing something like this:
// Temporarily enable the field to set the value of the TextArea
logTextArea.setEnabled(true);
String remarks = // my string to add into the box
if (remarks.length() > 0) {
logTextArea.setEnabled.setValue(remarks);
}
// set read-only again
logTextArea.setEnabled.setEnabled(false);
I also have to work out how many lines I now span and explicitly set the height of the box (via setVisibleLines()). I have now found that it does not word-wrap, so I've had to add some more horrible bodge-code to further split up this string.
So I'm writing code to emulate functionality that comes for free on a normal writable TextArea. Has anyone else found this issue after setting a text-field read-only? Is there another widget I could possibly use to display a list of read-only strings that will auto resize and auto wrap for me?
Many thanks for your time,
tom
Text Area is fine for re-sizing and auto word wrap, even you have your text
area as read only.
Tested now by creating a test project for gwt and it is working fine.
Also Word Wrap is the default behavior of Text area if you want to turn it off then you need to explicitly do this "getElement().setAttribute("wrap","off");
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.
