[Panels] New line not getting processed

thresh0ld · **Author**

Noticed something strange. On the first two examples, the special character '\n' is processed and a new line is inserted on the panel. On the last example, the string now is retrieved from a configuration file (key value) then passed to the function, it does not get processed. Why is this?

First Example (Gets Processed):

Code:

panel.DrawText("Test\nHeader");

Second Example (Gets Processed):

Code:

char tmpHeader[255];
Format(tmpHeader, sizeof(tmpHeader), "Test\nHeader");
panel.DrawText(tmpHeader);

Third Example (Does not get processed):

Note: g_StatPanelTitleMenuHeader1 would contain the text "Test\nHeader"

Code:

char g_StatPanelTitleMenuHeader1[255];

void LoadConfigData() {
	//....................
	
	//Extract
	kv.GetString("title_menu_header_1", g_StatPanelTitleMenuHeader1, sizeof(g_StatPanelTitleMenuHeader1));
	if (strcmp(g_StatPanelTitleMenuHeader1, "", false) == 0) {
		Debug("Config 'title_menu_header_1' is empty. Using default");
		FormatEx(g_StatPanelTitleMenuHeader1, sizeof(g_StatPanelTitleMenuHeader1), DEFAULT_TITLE_STAT_PANEL_MENU_HEADER);
	}
	
	//..............
}

bool DrawPanelHeader(Panel & panel, const char[] headerFormat, StringMap & map = null) {
	char header[255];
	ParseTitle(headerFormat, header, sizeof(header));
	
	if (map != null) {
		float totalPoints = 0.0;
		char name[MAX_NAME_LENGTH];
		int rankNum;
		
		//Perform some replacements
		if (map.GetValue(STATS_TOTAL_POINTS, totalPoints)) {
			char sTotalPoints[64];
			PSFormat(sTotalPoints, sizeof(sTotalPoints), "{f}", totalPoints);
			ReplaceString(header, sizeof(header), "{points}", sTotalPoints, false);
		}
		
		if (map.GetString(STATS_LAST_KNOWN_ALIAS, name, sizeof(name))) {
			ReplaceString(header, sizeof(header), "{name}", name, false);
		}
		
		if (map.GetValue(STATS_RANK, rankNum)) {
			char sRankNum[32];
			IntToString(rankNum, sRankNum, sizeof(sRankNum));
			if (totalPoints <= 0)
				ReplaceString(header, sizeof(header), "{rank}", "N/A", false);
			else
				ReplaceString(header, sizeof(header), "{rank}", sRankNum, false);
		}
	}
	
	if (!StringBlank(header)) {
		panel.DrawText(header);
		return true;
	}
	
	return false;
}

Example usage:

Code:

LoadConfigData();

StringMap map = new StringMap();

//populate map entries...

//Draw header
DrawPanelHeader(panel, g_StatPanelTitleMenuHeader1, map);

Output:
