How can I create new styles for pen, borland in VCL?
LOGPEN LogPen;
LogPen.lopnStyle = psDash;
LogPen.lopnWidth = Point(1,1);
LogPen.lopnColor = RGB(235, 115, 5);
SelectObject(Form1->Image1->Canvas->Handle, CreatePenIndirect(&LogPen));
You should be using the TPen properties instead of calling SelectObject() directly:
TPen *Pen = Form1->Image1->Canvas->Pen;
Pen->Style = psDash;
Pen->Width = 1;
Pen->Color = (TColor) RGB(235, 115, 5);
TPen::Style supports a range of different values:
psSolid, psDash, psDot, psDashDot, psDashDotDot, psClear, psInsideFrame, psUserStyle, psAlternate
The closest you can get to creating new styles for a pen is to use ExtCreatePen() to create an HPEN handle from custom style data, and then assign that to the TPen::Handle property.

I'm trying to add a chart to a docx file using docx4j. I generated what i wanted in Word and with the help of the docx4j webapp i was able to get the corresponding java code. Unfortunately the generated docx file is said to be corrupted by Word. When trying to debug, I realised that if I commented out the line that added the drawing to the run, the file became readable. I can't figure out what's wrong. Below is my code and the link to what i tried to reproduce http://www.filedropper.com/graphique .
I'm using docx4j 8.2 and office 2016

How to pass variable from another lua file? Im trying to pass the text variable title to another b.lua as a text.
a.lua
local options = {
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
b.lua
local score_label_2 = display.newText({parent=uiGroup, text=title, font=native.systemFontBold, fontSize=128, align="center"})
There are a couple ways to do this but the most straightforward is to treat 'a.lua' like a module and import it into 'b.lua' via require
For example in
-- a.lua
local options =
{
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
return options
and from
-- b.lua
local options = require 'a'
local score_label_2 = display.newText
{
parent = uiGroup,
text = options.title,
font = native.systemFontBold,
fontSize = 128,
align = "center"
}
You can import the file a.lua into a variable, then use it as an ordinary table.
in b.lua
local a = require("a.lua")
print(a.options.title)
I am trying to make a custom widget: for displaying a processor register which has a name, a value and can be displayed in octal/decimal hexa. The code is shown at the bottom. I receive better result when I use the code as shown (i.e I insert QRadioButtons):
If I use
mainLayout->addWidget(DisplayMode);
instead (I guess this is the correct method) then the resulting picture is
Do I misunderstand something? What is wrong?
RegisterWidget::RegisterWidget(QWidget *parent)
:QFrame (parent)
{
mValue = 0;
mName = "";
setFrameStyle(QFrame::Panel | QFrame::Sunken);
QHBoxLayout *mainLayout = new QHBoxLayout(this);
label = new QLabel(tr("mName"),this);
label->setText(mName);
label->setLineWidth(2);
QGroupBox *DisplayMode = new QGroupBox("");
QRadioButton *OctalR = new QRadioButton(this);
QRadioButton *DecimalR = new QRadioButton(this);
DecimalR->setChecked(true); DecimalR->setDown(true);
QRadioButton *HexaR = new QRadioButton(this);
QHBoxLayout *hbox = new QHBoxLayout;
hbox->addWidget(OctalR);
hbox->addWidget(DecimalR);
hbox->addWidget(HexaR);
hbox->addStretch(1);
DisplayMode->setLayout(hbox);
mainLayout->addWidget(label);
Value = new QLCDNumber(this);
Value->setDigitCount(8);
Value->setSegmentStyle(QLCDNumber::Flat);
Value->display(mValue);
mainLayout->addWidget(Value);
/* mainLayout->addWidget(DisplayMode);*/
mainLayout->addWidget(OctalR);
mainLayout->addWidget(DecimalR);
mainLayout->addWidget(HexaR);
setLineWidth(3);
setLayout(mainLayout);
connect(OctalR, SIGNAL(clicked()), this, SLOT(setOctal()));
connect(DecimalR, SIGNAL(clicked()), this, SLOT(setDecimal()));
connect(HexaR, SIGNAL(clicked()), this, SLOT(setHexa()));
}
Call QLayout::setContentsMargins() for both mainLayout and hbox. Try (3, 3, 3, 3) as parameters for a starting point and tweak. Layouts have default margins of 11 pixels on most platforms, according to the docs.

I am trying to generate a Livetile image from background task.
However, the generated PNG file only looks transparent, no single dot is painted at all.
So, I simplified the important code as below to test, yet no result was changed.
I imported Microsoft.Canvas.Graphics(+Effects,+Text),
Dim device As CanvasDevice = New CanvasDevice()
Dim width = 150, height = 150
Using renderTarget = New CanvasRenderTarget(device, width, height, 96)
Dim ds = renderTarget.CreateDrawingSession()
'ds = DrawTile(ds, w, h)
Dim xf As CanvasTextFormat = New CanvasTextFormat()
xf.HorizontalAlignment = CanvasHorizontalAlignment.Left
xf.VerticalAlignment = CanvasVerticalAlignment.Top
xf.FontSize = 12
renderTarget.CreateDrawingSession.Clear(Colors.Red)
ds.Clear(Colors.Blue)
ds.DrawText("hi~", 1, 1, Colors.Black, xf)
renderTarget.CreateDrawingSession.DrawText("hi~", 1, 1, Colors.Black, xf)
Await renderTarget.SaveAsync(Path.Combine(ApplicationData.Current.LocalFolder.Path, "_tile_150x150.png"))
End Using
The file is created, but it's filled with neither Red or Blue. No text at all. It's transparent with only 150x150 pixel canvas.
Is there any problem with the code? or any other reason?
Thanks a lot!
The CanvasDrawingSession ("ds" in your sample) needs to be Closed / Disposed before you call SaveAsync.
You can use "Using ds = renderTarget.CreateDrawingSession()" to do this for you - put the call to SaveAsync after "End Using".
From there you should use the same "ds" rather than call "CreateDrawingSession" multiple times.

Finally I solved my answer with this.
((LineSeries)MyChart.Series[0]).IndependentAxis = new LinearAxis
{
Minimum = 1,
Maximum = 5,
Orientation = AxisOrientation.X,
Interval = 1,
Margin = new Thickness(10, 0, 10, 0)
};
((LineSeries)MyChart.Series[0]).Clip = null;
((LineSeries)MyChart.Series[0]).Margin = new Thickness(10, 0, 10, 0);
I am drawing line chart with help of WinRT XAML Toolkit. I am setting X axis manually, but when I set I am getting wierd start & end point. I tried to set margin and padding but it's not working. Will you please suggest me how can I do that ?
((LineSeries)MyChart.Series[0]).IndependentAxis = new LinearAxis
{
Minimum = 1,
Maximum = 5,
Orientation = AxisOrientation.X,
Interval = 1,
//Margin = .... Not working
//Padding = .... Not working
};
I'd use a visual tree debugger to walk up the visual tree from these data points to see where the Clip property is set. In fact I just did that on the samples project and it is set on the LineSeries. See if it's set as part of its XAML template or if it is done in C# and remove it there. Also you could change the Minimum/Maximum values on your X axis to make more space. I'll add cleaning this all up to my TODO list.
