Command Line output supports Bold or underscore font? about librecad_3

[feragon]

It doesn't support RTF out of the box.
I tested this and it worked: https://stackoverflow.com/questions/1956542/how-to-make-item-view-render-rich-html-text-in-qt

If you need it, add the delegate to ui->history in lcUI/widgets/clicommand.cpp

[Guruprasad-Rane]

I will try this.

[Guruprasad-Rane]

By the way I could not achieve this. I was looking for such option so that when command line gives options to the user, it highlights using bold or underline font, the short cut options and the currently active option.
Example:
Options: < Radius >, Diameter
Is there already any function to do this?

[feragon]

Use this file for lcUI/widgets/clicommand.cpp: https://gist.github.com/feragon/0790b191c3cc400ba5c4ad2fba54d905

Try to enter some HTML command to test it (like <b>command</b>)

[Guruprasad-Rane]

Yes. It worked perfectly :-)

Couple of issues noticed.

• Line spacing between messages has increased considerably. Tried doc.setDefaultStyleSheet but didn't work. Also tried doc.setDocumentMargin(0); but no sucess.

• Scrollbar get added after few messages and it does not auto scroll. I guess this is because of increased line spacing only.

[feragon]

The auto scroll wasn't properly before. You have to scroll down one or two times to enable it.

Can you try to replace the HTMLDelegate sizeHint method with this :

QSize HTMLDelegate::sizeHint(const QStyleOptionViewItem& option, const QModelIndex& index) const {
    QTextDocument doc;
    doc.setHtml(option.text);
    doc.setTextWidth(option.rect.width());
    return {(int) doc.textWidth(), (int) doc.size().height()};
}

Before changing QSize HTMLDelegate::sizeHint

After changing QSize HTMLDelegate::sizeHint "Provide Center Point" is almost hidden because of overlap.

To reduce the line spacing I have tried

message("<b>CIRCLE</b><br>Provide Center Point:", self.target_widget)

[feragon]

Did you tried without the <br> ? You can call message two times (one call per line)

I'll look at changing sizeHint method to support multi-lines items.

[Guruprasad-Rane]

With out
with separate message calls

[Guruprasad-Rane]

I tried changing ui->history from QListWidget to QTextEdit in readonly mode and I think it works better. Scrollbar appears but it can be made to autoscroll to the last line. Also history need not be trimmed.

[Guruprasad-Rane]

history = new QTextEdit(dockWidgetContents);

void CliCommand::write(const QString& message) {
    ui->history->setHtml(ui->history->toHtml() + message);
    ui->history->verticalScrollBar()->setValue(ui->history->verticalScrollBar()->maximum());
}

[feragon]

It looks exactly the same. Do you need the HTML delegate with the QTextEdit ?

You can use the QTextEdit, I don't see any problem with it.

[Guruprasad-Rane]

No need for HTML delegate with QTextEdit, it can use toHtml()

Key Up and Key Down event for CliCommand::onKeyPressed(QKeyEvent *event) not working.
It has a condition if(_historyIndex + 1 < _history.size()) but _historyIndex is always -1 and _history.size() is always 0
What is _historyIndex and _history.size() ? And why this condition?

[feragon]

The up and down keys allow to move into the last typed commands.
_history should contains every typed command, and _historyIndex is the current position in the history.
If _history.size() is always 0, that means the commands are not added to the history anymore.
